| Abstract: | In this paper electron capture on iron group nuclei in crusts ofneutron stars in a strong magnetic field is investigated. Theresults show that the magnetic fields have only a slight effect onelectron capture rates in a range of 10$^{8}-10^{13}$G on surfaces ofmost neutron stars, whereas for some magnetars the magnetic fieldsrange from 10$^{13}$ to 10$^{18}$~G. The electron capture rates ofmost iron group nuclei are greatly decreased, reduced by even fourorders of magnitude due to the strong magnetic field. |
