摘要
以核素^56Co和^59Fe为例，讨论了强磁场中子星外壳层电子俘获．结果表明，绝大部分中子星表面的磁场范围10^4～10^9T，磁场对电子俘获率的影响很小．对于一些磁场范围为10^9～10^14T的超磁星，磁场可使电子俘获率大大降低，甚至可以降低3个量级．
The electron capture of the nuclide 56Co and 59Fe, as the examples, are investigated in a strong magnetic field at the crusts of Neutron stars. The results show that the magnetic field has only a slight effect on the electron capture rates at the range of the magnetic fields （ 10^4-10^14 T） on surfaces of the most neutron stars. Whereas for some magnetars, the range of the magnetic field is 10^9-10^14 T, the electron capture rates would be debased greatly and maybe even decreased for 3 order magnitudes by the strong magnetic field.
