Abstract:
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(104—1014 T)on surfaces of the most neutron stars.Whereas for some magnetars,the range of the magnetic field is 109—1014 T,the electron capture rates would be debased greatly and maybe even decreased for 3 order magnitudes by the strong magnetic field.
