在Skyrme有效相互作用的中心部分和自旋轨道部分中加入张量部分,分析了张量部分对球形自旋不饱和核Hartree-Fock自旋轨道耦合的贡献.如果张量相互作用的强度被视为自由参数,则可以实现自旋轨道分裂的微小改进,但是如果张量相互作用的贡献被估计为现实的相互作用,则与实验的拟合恶化。
A tensor part is added to central and spin-orbit parts of Skyrme's effective interaction and its contribution to the Hartree-Fock spin-orbit coupling of spherical spin-unsaturated nuclei is analysed. Minor improvements to spin-orbit splittings can be achieved if the strengths of the tensor interaction are treated as free parameters, but the fit to experiment deteriorates if the tensor interaction contribution is estimated for a realistic interaction.
