B. Yilmaz, S. Ayik, D. Lacroix, O. Yilmaz

摘要:

利用随机平均场方法研究了对称重离子碰撞中的核子交换机制。将前人的工作推广到偏离中心碰撞,推导出核子交换机制扩散系数的解析表达式。对${}^{40}$ Ca + ${}^{40}$ Ca和${}^{90}$ Zr + ${}^{90}$ Zr体系进行了数值计算,并与唯象核子交换模型的计算结果进行了比较.此外,计算与现有的实验结果的深非弹性碰撞之间的钙核。

英文摘要:

Nucleon exchange mechanism is investigated in deep-inelastic symmetric heavy-ion collisions in the basis of the Stochastic Mean-Field approach. By extending the previous work to off-central collisions, analytical expression is deduced for diffusion coefficient of nucleon exchange mechanism. Numerical calculations are carried out for ${}^{40}$Ca + ${}^{40}$Ca and ${}^{90}$Zr + ${}^{90}$Zr systems and the results are compared with the phenomenological nucleon exchange model. Also, calculations are compared with the available experimental results of deep-inelastic collisions between calcium nuclei.
