基于超强磁场（UMFs）相对论和随机相位近似（RPA）理论，利用Shell-Model Monte Carlo （SMMC）方法，研究了超强磁场对核素55co和56ni在磁星中的电子俘获（EC）和电子分数变化率（REFC）的影响。在狄拉克δ函数和泡利不相容原理的基础上，讨论了磁星中UMFs对电子费米能的影响。研究结果表明，复合纳米粒子能显著提高材料的EC速率，甚至超过5个数量级。由于umf的存在，REFC降低了6个数量级以上。
Basing on the theory of relativity in ultrastrong magnetic fields (UMFs) and Random Phase Approximation (RPA), by using the Shell-Model Monte Carlo (SMMC) method, the influence of UMFS on electron capture (EC) and the rates of electron fraction change (REFC) of nuclides55Co and56Ni are investigated in magnetars. Basing on the Diracδ-function and Pauli exclusion principle, we also discuss the influence on electron Fermi energy by UMFs in magnetars. The results show that the EC rates are increased greatly and even exceed five orders of magnitude by UMFs. The REFC is decreased even more than six orders of magnitude due to UMFs.
