摘要
就中子物质计算并讨论了二体中心势中各成分对出现铁磁相变临界密度的影响.结果表明硬核的大小对临界密度起着关键性的作用.还计算了在M-S势作用下的中子物质出现铁磁相变的临界密度、含有铁磁相变的物态方程及中子星模型.所得的临界密度为k_F=5.45fm(-1),含磁化的中子星的最大质量低于不含磁化的中子星的最大质量.
The effect of each composition of two-body central potential on the critical density for ferromagnetic transition is calculated for neutron matter. The results show that the radius of the hard core plays an important role in the critical density. For neutron matter with M-S interaction, the critical density of the ferromagnetic transition, the equation of state and the neutron star models are calculated. The critical density k_F is 5.45fm^(-1). The maximum mass of the neutron star with the ferromagnetic phase is lower than that without the ferromagnetic phase.
