在Hartree-Fock加BCS近似下，利用Skyrme力类型的示意有效力，研究了中子星内壳中物质的性质。特别注意对物质分布的均匀描述和非均匀描述之间的区别。为此，在球形Wigner-Seitz盒中进行了自洽Hartree-Fock计算。将计算结果与相应的Thomas-Fermi计算结果进行了比较。讨论了壳层结构对非均匀物质中配对关联形成的影响。
Properties of the matter in the inner crust of a neutron star are investigated in a Hartree-Fock plus BCS approximation employing schematic effective forces of the type of the Skyrme forces. Special attention is paid to differences between a homogenous and inhomogeneous description of the matter distribution. For that purpose self-consistent Hartree-Fock calculations are performed in a spherical Wigner-Seitz cell. The results are compared to predictions of corresponding Thomas-Fermi calculations. The influence of the shell structure on the formation of pairing correlations in inhomogeneous matter are discussed.
