摘要

Following the theory of relativity,in the presence of an ultrastrong magnetic field (UMF) and utilizing a nuclear shell model,we carry out an estimation of the neutrino energy loss (NEL) rates of nuclides 53-60Cr,which occur by electron capture in magnetars.The results show that the NEL rates greatly increase when a UMF is present,and can even exceed nine orders of magnitude at relatively lower density and temperature (e.g.ρ7 =5.86,Ye =0.47,T9 =7.33) in the range from 1013 G to 1018 G.However,the increase in rates was no more than six orders of magnitude at relatively higher density and temperature (e.g.ρ7 =4.86 × 108,Ye =0.39,T9 =14.35).
