Z=14和N=28链单粒子谱演化的平均场研究
A mean field study of single-particle spectra evolution in Z=14 and N=28 chains
摘要：
我们研究了42 Si中质子1d（3/2）-1d（5/2）自旋轨道分裂和中子1f（7/2）亚壳层闭合的减少机制。我们使用各种自洽的平均场模型：非相对论Skyrme-Hartree-Fock和相对论密度相关的Hartree-Fock。特别注意的是致力于张量分量的有效相互作用的影响。结果表明，张量力确实控制着1d质子自旋轨道分裂的减少。另一方面，中子1f（7/2）次壳层闭合的减少与张量力没有明显的关系。
英文摘要：
We study the mechanisms which reduce the proton 1d(3/2)-1d(5/2) spin-orbit splitting and the neutron 1f(7/2) subshell closure in 42Si. We use various self-consistent mean field models: non-relativistic Skyrme-Hartree-Fock and relativistic density-dependent Hartree-Fock. Special attention is devoted to the influence of a tensor component in the effective interaction. It is found that the tensor force indeed governs the reduction of the 1d proton spin-orbit splitting. On the other hand, the reduction of the neutron 1f(7/2) subshell closure is not clearly related to the tensor force.
