Abstract

Single neutron- and proton-removal cross sections have been systematically measured for 72 medium-mass neutron-rich nuclei around Z=50 and energies around 900A MeV using the FRagment Separator (FRS) at GSI. Neutron-removal cross sections are described by considering the knock-out process together with initial- and final-state interactions. Proton-removal cross sections are, however, significantly smaller than predicted by the same calculations. The observed difference can be explained as due to the knockout of short-correlated protons in neutron-proton dominating pairs.

Abstract

We present a new experimental method to correlate the isotopic composition of intermediate mass fragments (IMF) emitted at mid-rapidity in semi-peripheral collisions with the emission timescale: IMFs emitted in the early stage of the reaction show larger values of $<$N/Z$>$ isospin asymmetry, stronger angular anisotropies and reduced odd-even staggering effects in neutron to proton ratio $<$N/Z$>$ distributions than those produced in sequential statistical emission. All these effects support the concept of isospin "migration", that is sensitive to the density gradient between participant and quasi-spectator nuclear matter, in the so called neck fragmentation mechanism. By comparing the data to a Stochastic Mean Field (SMF) simulation we show that this method gives valuable constraints on the symmetry energy term of nuclear equation of state at subsaturation densities. An indication emerges for a linear density dependence of the symmetry energy., Comment: 17 pages, 7 figures; submitted to Physical Rev. C

Abstract

The fragmentation of neutron-rich 132Sn nuclei produced in the fission of 238U projectiles at 950 MeV/u has been investigated at the FRagment Separator (FRS) at GSI. This work represents the first investigation of fragmentation of medium-mass radioactive projectiles with a large neutron excess. The measured production cross sections of the residual nuclei are relevant for the possible use of a two-stage reaction scheme (fission+fragmentation) for the production of extremely neutron-rich medium-mass nuclei in future rare-ion-beam facilities. Moreover, the new data will provide a better understanding of the "memory" effect in fragmentation reactions., Comment: 5 pages, 3 figures

5. Influence of the Coulomb Interaction on the Chemical Equilibrium of Nuclear Systems at Break-Up

Author

Tõke, J., Gawlikowicz, W., and Schröder, W. U.

Subjects
Nuclear Theory
Abstract

The importance of a Coulomb correction to the formalism proposed by Albergo et al. for determining the temperatures of nuclear systems at break-up and the ensities of free nucleon gases is discussed. While the proposed correction has no effect on the temperatures extracted based on double isotope ratios, it becomes non-negligible when such temperatures or densities of free nucleon gases are extracted based on multiplicities of heavier fragments of different atomic numbers.

Abstract

International audience; The production cross sections of neutron-rich fission residues in reactions induced by U238 projectiles at 950A MeV impinging on Pb and Be targets are investigated at the Fragment Separator at GSI. These two targets allow us to investigate fission processes induced by two reaction mechanisms, Coulomb and nuclear excitations, and to study the role of these mechanisms in the neutron excess of the final fragments.

Abstract

Background: In heavy-ion collisions at intermediate energies the production of light charged particles and intermediate mass fragments (IMFs) is due to different reaction mechanisms and different time scales, ranging from fast dynamical processes to statistical emission from the equilibrated system. Purpose: We compare the IMF statistical and dynamical emission probabilities in collisions of a neutron-rich Sn124+Ni64 system and a neutron-poor Sn112+Ni58 system at the laboratory energy of 35 A MeV. Method: The IMFs production mechanism in semiperipheral reactions has been investigated in our previous works. In this paper, the analysis is expanded for the same set of data and production cross sections have been evaluated for dynamical and statistical emission in a coherent way for light and heavy fragments. Results: The data analysis has evidenced a strong competition between dynamical and statistical emission mechanisms. Probability of the dynamical emission of IMFs is strongly influenced by the (N/Z) ratio of the colliding system. Conclusions: It is demonstrated that the statistical emission is equally probable for the two systems, while the dynamical emission is enhanced for the neutron-rich system, especially for heavy fragments (Z≥6). The observed effect points at a high sensitivity of the prompt-dynamical emission to the (N/Z) ratio of a given system. © 2015 American Physical Society.

Abstract

The fragmentation of neutron-rich Sn-132 nuclei produced in the fission of U-238 projectiles at 950 A MeV has been investigated at the FRagment Separator (FRS) at GSI. This work represents the first investigation of fragmentation of medium-mass radioactive projectiles with a large neutron excess. The measured production cross sections of the residual nuclei are relevant for the possible use of a two-stage reaction scheme (fission + fragmentation) for the production of extremely neutron-rich medium-mass nuclei in future rare-ion-beam facilities. Moreover, the new data will provide a better understanding of the memory effect in fragmentation reactions. (C) 2011 Elsevier B.V. All rights reserved.

Abstract

International audience; Collisions of a very heavy nonfusing nuclear system 197Au + 197Au were studied at an energy of 15MeV/ nucleon. An interesting process of violent reseparation of this heavy system into three or four fragments of comparable size was observed. In the case of ternary partitioning, either the projectile-like fragment (PLF) or target-like fragment (TLF) breaks up almost collinearly with the PLF-TLF separation axis. In the case of quaternary reactions, both PLF and TLF were observed breaking up along this direction. By comparison with a dynamical model of deep inelastic collisions it was concluded that the ternary and quaternary reactions occur in semiperipheral collisions, in a range of angular momenta corresponding to about 0.5–0.7 of the maximum L value for grazing collisions. The time elapsing from the scission of the binary PLF + TLF system to the secondary scission of PLF or TLF was estimated to be of about 70–80 fm/c for the ternary reactions and 80–100 fm/c for the quaternary reactions.

Abstract

A quantitative comparison is made between the absolute cross sections associated with statistical and dynamical emission of heavy fragments in the 124Sn+64Ni and 112Sn+58Ni collisions experimentally investigated at 35A MeV beam energy using the multidetector CHIMERA. The result shows that the dynamical process is about twice as probable in the neutron-rich 124Sn+64Ni system as in the 112Sn+58Ni neutron-poor one. This unexpected and significant difference indicates that the reaction mechanism is strongly dependent on the entrance-channel isospin (N/Z) content.

Abstract

Intermediate mass fragments (IMF) emitted with multiplicity MIMF ≥ 3 at mid-velocity in semi-central reactions induced by 124Sn projectile (35 A.MeV) on 64Ni target have been studied. The results show a clear correlation between the fragment sizes and the corresponding transverse velocities. We interpret this correlation as signature of hierarchy effects in nuclear multifragmentation. A correlation with the fragments isospin contents is also found. Qualitative comparisons with SMF calculations suggests that these correlations are good observables for the symmetry term of the EOS at sub-saturation density.

Abstract

International audience; This paper presents the physical analysis results for the following reactions: 124Sn + 64Ni, 124Sn + 27Al, 124Sn + 58Ni at 35 MeV/A and 25 MeV/A. The main goal of this studies was to find observables sensitive to isospin effects and to present the similarities/differences between the systems characterised by various charge asymmetry factor, defined as I = (N-Z)/A. Theoretical simulations based on the Quantum Molecular Dynamics (QMD) model have been performed in order to compare them with the results of the analysis of experimental data. The first phase of the reaction was carried out with the code CHIMERA [1]. The sequential decay of hot fragments was simulated by the code COOLER [2]. The conclusions are as follows: there are observables sensitive to the isospin of the system, such as the Light Charged Particles (LCP) emission and their sensitivity is demonstrated more prominently in the analysis of central collisions at 35 MeV/A. The theoretical calculations do not reproduce these relations well.

Abstract

Expérience au LNS; International audience; A new reaction mechanism of violent reseparation of a heavy nucleus-nucleus system, $^{197}$Au + $^{197}$Au, into three or four massive fragments in collisions at 15 MeV=nucleon has been observed. After reseparation, the fragments are almost exactly aligned, thus showing a very short time scale of the reseparation process, of about 70–80 fm=c.

Abstract

International audience; For fragments emitted in the reactions 124Sn + 64Ni and 112Sn + 58Ni at 35 AMeV, isotopic composition and velocity correlations have been studied as a function of the centrality of the collision, using the 4\pi Chimera multidetector. We have investigated the time scale for fragments formation, in order to distinguish between prompt dynamical and sequential statistical emission. Promptly emitted light fragments (Z \leq 9) produced in the mid-rapidity domain are characterised by larger N/Z ratio and stronger angular anisotropies than those produced in sequential statistical emission. Results are compared with stochastic BNV code simulations obtained for primary fragments. Valuable information on the symmetry term of the nuclear equation of state at sub-saturation densities are obtained.

Abstract

The production cross sections of neutron-rich fission residues produced in reactions induced by a U-238 beam impinging onto Pb and Be targets were investigated at the Fragment Separator (FRS) at GSI. These data allowed us to discuss the optimum energies in fission for producing the most neutron-rich residues. 4th International Workshop on Nuclear Fission and Fission-Product Spectroscopy, May 13-16, 2009, Cadarache, France

Abstract

Experiments with radioactive nuclear beams have enabled us to investigate nuclear properties far from stability. Glauber model analysis of total interaction cross sections measurements provides a useful method to determine effective matter radii. In this work we have taken advantage of the relativistic heavy ion facility at GSI for producing and investigate total interaction cross sections of more than hundred medium-mass nuclei along long isotopic chains.

Abstract

The fragmentation of neutron-rich Sn isotopes obtained from the fission of (238)U projectiles at 950 MeV/u has been investigated at the FRagment Separator (FRS) at GSI. In order to study the feasibility of a two-step reaction scheme for the production of medium-mass neutron-rich nuclei, fragments with masses A approximate to 130 have been isotopically resolved in the first part of FRS and their fragmentation residues identified in the second part. 43rd Zakopane Conference on Nuclear Physics, Sep 01-07, 2008, Zakopane, Poland
