Abstract

We discuss experimental data concerning 40,48Ca+ 40,48Ca reactions at 25 MeV/nucleon; the 4π multi-detector Chimera has been used as detection device. Effects that can be attributed to the neutron to proton ratios (N/Z) degree of freedom have been investigated. From the analysis of experimental data it seems that the neutron richness of the interacting system plays an important role on the evolution of fusion-like sources formed in semi-central collisions. In particular, it is observed that the larger is the neutron content and the larger is the emission of heavy residues. Experimental data have been compared with CoMD-II model calculations; a moderately stiff symmetry energy should be used to reproduce satisfactorily the data. A thermodynamical analysis on fusion-like sources has been also performed. In semi-peripheral collisions, isospin diffusion signals have been found. They have been investigated by analyzing isobaric emission ( 7Li/7Be) of quasi-projectile sources. Experimental data indicate that an incomplete N/Z mixing is reached during the interaction phase.

Abstract

International audience; The elliptic-flow ratio of neutrons with respect to protons or lightcomplex particles in reactions of heavy ions at pre-relativistic energieshas been proposed as an observable sensitive to the strength of thesymmetry term of the nuclear equation of state at supra-saturationdensities. In the ASY-EOS experiment at the GSI laboratory, flows ofneutrons and light charged particles were measured for 197Au+197Au,96Zr+96Zr and 96Ru+96Ru collisions at 400 MeV/nucleon with theLarge Area Neutron Detector LAND as part of a setup with severaladditional detection systems used for the event characterization. Flowresults obtained for the Au+Au system, in comparison with predictionsof the UrQMD transport model, confirm the moderately soft to lineardensity dependence of the symmetry energy deduced from the earlierFOPI-LAND data.

Abstract

In past experiments, mass asymmetric projectile-target combinations 124Sn+64Ni and 112Sn+58Ni were investigated at ELab(112,124Sn)=35 A.MeV beam energy by using the 4π multi-detector CHIMERA. From a quantitative comparison of cross sections associated to Statistical and Dynamical Fission of the Projectile-Like Fragments, it resulted that Dynamical Fission process is about two times more probable in the neutron rich 124Sn+64Ni system than in the 112Sn +58 Ni neutron poor one. In contrast, no sizable difference was found for Statistical Fission mechanism. The observed difference in the strength of the Dynamical effects could arise from the difference in entrance channel Isospin (N/Z) content. In order to disentangle Isospin effects from effects due to the different masses of the two systems, a new experiment 124Xe+64Zn at 35 A.MeV beam energy has been recently carried out.

Abstract

Effects related to the neutron to proton ratio (N/Z) degree of freedom in 40, 48Ca+40, 48Ca reactions at 25 MeV/nucleon have been investigated. Isotopic effect and even-odd staggering characterize the emission of light fragments at forward angles. The study of isobaric ratio 7Li/7Be for quasi-projectile source in semi-peripheral event of reactions allows moreover to investigate isospin diffusion effects in heavy ion collisions. © Owned by the authors, 2012.
