The role of the tensor part of the nuclear interaction is actively investigated in recent years due to experimental advancement yielding new data in nuclei far from the β-stability line. In this article we study the effect of this part of the nuclear interaction on deformed neutron magic numbers in the rare-earth region within the Skyrme energy-density functional for various TIJ [T. Lesinski, M. Bender, K. Bennaceur, T. Duguet, and J. Meyer, Phys. Rev. C 76, 014312 (2007)] parametrizations. Two quantities signaling magic numbers are considered: two-neutron separation energies and single-particle energies. They are calculated in isotopic series involving well-deformed rare-earth nuclei ranging from Z=64 to Z=72 in the N=100 region. Obtained results show that, whereas the neutron-proton tensor contribution to binding energies is important to reproduce neutron subshell closure at N=104 in heavier rare earths Yb(Z=70) and Hf(Z=72) isotopes, like-particle tensor also plays a role in the single-particle spectrum around Fermi level and is even favored in lighter Gd(Z=64) and Dy(Z=66) rare-earth isotopes.

Skyrme 能量密度泛函张量项对稀土地区中子变形幻数的作用

近年来,由于实验的进步,核相互作用中张量部分的作用得到了积极的研究,在远离原子核的核中产生了新的数据。 β- 稳定线。在本文中,我们研究了这部分核相互作用对各种 TIJ 的 Skyrme 能量密度泛函中稀土区域变形中子幻数的影响 [T. Lesinski、M. Bender、K. Bennaceur、T. Duguet 和 J. Meyer,物理学。Rev. C 76 , 014312 (2007)] 参数化。考虑了两个表示幻数的量:双中子分离能量和单粒子能量。它们是在同位素系列中计算的,涉及变形良好的稀土原子核,范围从Z=64Z=72 在里面 N=100地区。获得的结果表明,虽然中子 - 质子张量对结合能的贡献对于在N=104 在较重的稀土中 (Z=70)高频(Z=72) 同位素,类粒子张量也在费米能级附近的单粒子光谱中起作用,甚至在较轻的 (Z=64)染料(Z=66) 稀土同位素。
