射弹破碎模型:Ni对Ta,Be和Ni对Al的情况研究

Model for projectile fragmentation: case study for Ni on Ta, Be and Xe on Al

S. Mallik, G. Chaudhuri, S. Das Gupta

摘要:

对于弹丸碎片,我们制定了一个模型的细节,其起源可以追溯到Bevalac时代。该模型介于唯象EPAX参数化和微观输运模型如“重离子相空间探索模型”(HIPSE)和反对称分子动力学(AMD)之间。我们应用该模型的一些最新的数据,在Ta和Be的射束能量为140 MeV/核子和一些旧的数据,在790 MeV/核子的射束能量的Al的粒子上的Ni的弹丸碎裂。得到了反应中各种复合材料的合理截面值。

英文摘要:

For projectile fragmentation we work out details of a model whose origin can be traced back to the Bevalac era. The model positions itself between the phenomenological EPAX parametrization and microscopic transport models like "Heavy Ion Phase Space Exploration Model" (HIPSE) and antisymmetrised molecular dynamics(AMD). We apply the model to some recent data of projectile fragmentation of Ni on Ta and Be at beam energy 140 MeV/nucleon and some older data of Xe on Al at beam energy 790 MeV/nucleon. Reasonable values of cross-sections for various composites populated in the reactions are obtained.
