弹丸破碎模型

A model for projectile fragmentation

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

摘要:

弹丸破碎模型的起源可以追溯到Bevalac时代。该模型介于唯象EPAX参数化和输运模型如“重离子相空间探测”(HIPSE)模型和反对称分子动力学(AMD)模型之间。一个非常简单的碰撞参量的输入温度的依赖性被纳入模型,这有助于分析更多的周边碰撞。应用该模型计算了不同能量下不同弹丸碎裂反应在不同Z_{bound}下的电荷、同位素分布、中等质量碎片平均数和最大团簇平均尺寸。

英文摘要:

A model for projectile fragmentation is developed whose origin can be traced back to the Bevalac era. The model positions itself between the phenomenological EPAX parametrization and transport models like "Heavy Ion Phase Space Exploration" (HIPSE) model and antisymmetrised molecular dynamics (AMD) model. A very simple impact parameter dependence of input temperature is incorporated in the model which helps to analyze the more peripheral collisions. The model is applied to calculate the charge, isotopic distributions, average number of intermediate mass fragments and the average size of largest cluster at different Z_{bound} of different projectile fragmentation reactions at different energies.
