description | 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 ß-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)PRVCAN0556-281310.1103/PhysRevC.76.014312] 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. |
