摘要
β decay in the strong magnetic field of the crusts of neutron stars is analysed by an improved method. The reactions ^67Ni(β-)^67Cu and ^62Mn(β-)^62Fe are investigated as examples. The results show that a weak magnetic field has little effect on β decay but a strong magnetic field (B 〉 10^12G) 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.
