超强磁场下的电子气体的化学势

摘要

化学势对电子俘获和Beta衰变过程等起着关键作用．本文对强磁场下的Landau量子化能级作了讨论，分析了超强磁场下非零温电子气体化学势，结果表明，在致密星环境下，磁场小于10^13高斯时，磁场对化学势的影响有限；当磁场大于10^13高斯时，化学势随磁场增加显著增加．较高密度、高密度下温度对化学势几乎无影响．%The paper discusses the effect of strong magnetic field on chemical potential. It is shown that, when B 〈 10^13G the magnetic fields have only a slight effect on electron chemical potential and electron capture, but when B 〉 10^13G electron chemical potential will increase greatly. What＇ s more the temperature has no effect on electron chemical potential.
