| 摘 要： | βdecay in the strong magnetic field of the crusts of neutron stars is analysed by an improved method. The reactions 67 Ni(β-)67 Cu and 62 Mnbeta -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 β decay rates obviously. The conclusion derived may be crucial to the research of late evolution of neutron stars and nucleosynthesis in r-process.
