A Model Comparison Study of Fragment Production in 140 A MeV super(58, 64)Ni+ super(9)Be Reactions

The cross sections of fragments produced in the 140 A MeV super(58,64)Ni+ super(9)B e projectile fragmentation reactions are calculated by using the antisymmetrized molecular dynamics (AMD) model, the modified statistical abrasion-ablation (SAA) model, and the empirical EPAX2/EPAX3 formulae. The Gog...

Summary:The cross sections of fragments produced in the 140 A MeV super(58,64)Ni+ super(9)B e projectile fragmentation reactions are calculated by using the antisymmetrized molecular dynamics (AMD) model, the modified statistical abrasion-ablation (SAA) model, and the empirical EPAX2/EPAX3 formulae. The Gogny-g0 interaction is taken as the effective nucleon-nucleon interaction in the AMD calculation, and the decays of fragments obtained from the AMD results are calculated by using the GEMINI code. The calculated cross sections of fragments are compared.
