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

We discuss results on the emission of light clusters in nuclear reactions 40 Ca + 40,48 Ca ,46 Ti at 25 MeV/nucleon. They were detected and identified in mass and charge by means of the CHIMERA 4π array. Inclusive emission at forward angles shows that isotopic yields of Li and Be nuclei are related to the N/Z values of entrance channels. Moreover, structure effects and even-odd staggering in charge distributions of intermediate mass fragments emitted at forward angles will be shown. In agreement with previous experimental findings, odd-even effects are clearly visible in N ≈ Z systems, while are less pronounced in the neutron rich collision 40 Ca +48 Ca . These experimental findings are compared to preliminary data obtained in 40 Ca +48 Ca . collision at 25 MeV/nucleon.
