Effect of strong magnetic field on chemical potential and electron capture in magnetar

doi:10.1088/1674-1056/19/9/099701

Abstract The chemical potential of electrons in a strong magnetic field is investigated. It is shown that the magnetic field has only a slight effect on electron chemical potential when B<10¹¹ T, but electron chemical potential will decrease greatly when B>10¹¹ T. The effects of a strong magnetic field on electron capture rates for ⁶⁰Fe are discussed, and the result shows that the electron capture sharply decreases because of the strong magnetic field.

Keywords: strong magnetic field electron chemical potential electron capture magnetar
