Abstract

The N=20 island of inversion is an excellent playground for testing shell model calculations. The Mg chain is a region of shell evolution still far from being well understood. In this paper we present preliminary results of a single-neutron knockout experiment from ³¹Mg performed at GANIL to study the structure of ³¹Mg and of the core ³⁰Mg. The level scheme and longitudinal momentum distributions were mesured and spectroscopic factors were deduced. Negative parity states arise at low energy and the spectroscopic factor for the isomeric 0²₊ in ³⁰Mg was determined to be smaller than foreseen in the standard picture. The preliminary experimental results are compared to state-of the art shell model calculations revealing opposed interpretations.

Abstract

Single-neutron and single-proton removal cross sections have been measured for medium-mass neutron-rich nuclei around Z=50 and energies around 1000A MeV using the FRagment Separator (FRS) at GSI. The measured cross sections confirm the relative low values of the proton-removal cross sections, observed since a long time ago and not yet understood. Model calculations considering the knock-out process together with initial- and final-state interactions describe the measured neutron-removal cross sections. Proton-removal cross sections are, however, significantly over-predicted by the same calculations. The observed difference can be explained to a large extent by the knock-out of short-range correlated nucleons from dominant neutron-proton pairs in neutron-rich nuclei. © 2020 The Author(s)

Abstract

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. © 2019 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

The radial evolution of the matter distributions with neutron excess has been investigated at GSI measuring total interaction cross sections for long isotopic chains of medium-mass nuclei. Comparisons with different model calculations show a clear increase of the total interaction cross sections for the most neutron-rich nuclei that we interpret as a signature for a larger matter radius of those nuclei.

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

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.
