Effect of strong magnetic field on electron capture of iron group nuclei in crusts of neutron stars

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.
