摘要:

用随机平均场方法研究了$^{238}$ U + $^{238}$ U中心碰撞中核子交换的量子扩散机制.对于在这项工作中考虑的轰击能量,双原子核结构在碰撞过程中保持。因此,可以将核子交换描述为质量和电荷不对称的扩散过程。量子中子和质子扩散系数,包括记忆效应,提取的SMF方法和主要的碎片分布计算。

英文摘要:

Quantal diffusion mechanism of nucleon exchange is studied in the central collisions of $^{238}$U + $^{238}$U in the framework of the stochastic mean-field (SMF) approach. For bombarding energies considered in this work, the di-nuclear structure is maintained during the collision. Hence, it is possible to describe nucleon exchange as a diffusion process for mass and charge asymmetry. Quantal neutron and proton diffusion coefficients, including memory effects, are extracted from the SMF approach and the primary fragment distributions are calculated.
