Influence of strong magnetic field on $\beta$ decay in the crusts of neutron stars

Abstract

Abstract $\beta$ decay in the strong magnetic field of the crusts of neutron stars is analysed by an improved method. The reactions ⁶⁷ Ni($\beta$^-)⁶⁷ Cu and ⁶² Mn($\beta$^-)⁶² Fe are investigated as examples. The results show that a weak magnetic field has little effect on βdecay but a strong magnetic field (B >10¹²G) increases $\beta$ decay rates obviously. The conclusion derived may be crucial to the research of late evolution of neutron stars and nucleosynthesis in r-process.
