Study on Isotopic Distribution Produced by Nucleus-Nucleus Collisions with Modified SAA Model

Abstract: Base on Brohm's Statistic-Ablation-Abrasion (SAA) model, the modified SAA model was developed via introducing the isospin dependence of nucleon distribution in nucleus and parameterized formulas for nucleon-nucleon cross section in nuclear matter. It can simulate well the isotopic distribution at both high and intermediate energies. By the improvement of computational method, the range of calculation of isotopic distribution can be increased from three order magnitude to eight order magnitude (even higher) . It can reproduce experimental data and predict the isotopic distribution for very far from stability line which is very important from experimental viewpoint.
