| 摘 要： | 以核素^55Co和^54Mn为例．讨论了强磁场下的中子星外壳层Gamow—Teller跃迁（G-T）电子俘获率．结果表明，对于大部分中子星，表面磁场（10^4～10^9T）对Cr-T跃迁电子俘获率的影响很小，对于超磁中子星．表面磁场（10^9～10^13T）使GT跃迁电子俘获率降低大约2—3个数量级．

| Abstract: | Taking the nuclide 55Co and 54Mn as examples,the rate of Gamow-Teller transition electron capture of the crusts of Neutron stars were in a strong magnetic field investigated.The results showed that at the range of the magnetic fields(104~109 T) on surfaces of the most neutron stars,the magnetic field has only a minor effect on the electron capture.However,at the magnetic field 109~1013 T range for some magnetars,the EC rates are decrease greatly even for 2~3 orders by the strong magnetic field. |
