论文摘要
$ {}^{}^{238} \ text {u}+{}^{}^{238} \ text {u} $系统的多核转移机制在基于定量的earkitield-field-field-field-field-field-field（以$ e} = 833 $ meV基于固定的方法的框架中，以$ e_ \ c.m。} = 833 $ meV进行了研究，以$ e_ \ c.m。} = 833 $ meV进行了研究。双横截面$σ（n，z）$作为中子和质子数的函数，跨段$σ（z）$和$σ（a）$作为原子数的函数，计算质量数以生产主要片段。计算指示$ {}^{238} \ text {u}+{}^{}^{238} \ text {u} $系统可能位于势能表面的不稳定平衡状态，沿$（n，z）上的beta稳定线沿着beta稳定线略有负曲率。这种行为可能导致沿Beta稳定性方向相当大的扩散。
Multinucleon transfer mechanism in the collision of ${}^{238}\text{U}+{}^{238}\text{U}$ system is investigated at $E_\text{c.m.} =833$ MeV in the framework of the quantal diffusion description based on the stochastic mean-field approach (SMF). Double cross-sections $σ(N,Z)$ as a function of the neutron and proton numbers, the cross-sections $σ(Z)$ and $σ(A)$ as a function of the atomic numbers and the mass numbers are calculated for production of the primary fragments. The calculation indicates the ${}^{238} \text{U}+{}^{238} \text{U}$ system may be located at an unstable equilibrium state at the potential energy surface with a slightly negative curvature along the beta stability line on the $(N,Z)-$plane. This behavior may lead to rather large diffusion along the beta stability direction.
