论文摘要
在模拟中子星环境的条件下研究了超重元素的合成。约束的分子动力学（COMD）方法用于模拟极度N型核的低能碰撞。当隐式引入中子星环境（库仑相互作用的筛选）时，会观察到由于“中子风”引起的新型融合屏障。当还引入周围核的背景时，核融合可能会降低到10 $^{8} $ k的温度，并且非常沉重和富含n的核的合成似乎是可行的。中子星环境中可能存在超重型核可以提供额外的相干中微子散射或其他机制的机制，从而导致X射线爆发或引力波信号，从而成为另一个关键过程，为中子星星进化的建议模型添加新信息。
The synthesis of hyper-heavy elements is investigated under conditions simulating neutron star environment. The Constrained Molecular Dynamics (CoMD) approach is used to simulate low energy collisions of extremely n-rich nuclei. A new type of the fusion barrier due to a "neutron wind" is observed when the effect of neutron star environment (screening of Coulomb interaction) is introduced implicitly. When introducing also a background of surrounding nuclei, the nuclear fusion becomes possible down to temperatures of 10$^{8}$ K and synthesis of extremely heavy and n-rich nuclei appears feasible. A possible existence of hyper-heavy nuclei in a neutron star environment could provide a mechanism of extra coherent neutrino scattering or an additional mechanism, resulting in X-ray burst or a gravitational wave signal and, thus, becoming another crucial process adding new information to the suggested models on neutron star evolution.
