Isospin effects on fragment production

Abstract

To understand the isospin effects in nearly symmetric nuclear matter we performed a complete systematical theoretical study within an Isospin dependent Quantum Molecular Dynamical Model (IQMD) and using Minimum Spanning Tree (MST) algorithm. Simulations are carried out for the reactions ${}_{124}S{n}^{50}{+}_{124}S{n}^{50}$ and ${}_{107}S{n}^{50}{+}_{124}S{n}^{50}$. The collision geometry is varied from central to peripheral. We find that neutron rich colliding nuclei are better candidate to study the isospin effects
