摘要: We study systematically the impact of time-even tensor terms Skyrme energy density functional, i.e., bilinear in spin-current density, on deformation properties closed-shell nuclei corresponding to $20,28,40,50,82$, and $126$ neutron or proton shell closures. compare results obtained with three different families parametrizations whose have been adjusted spherical nuclei: (i) $\mathrm{T}\mathit{IJ}$ interactions proposed first article this series [T. Lesinski et al., Phys. Rev. C 76, 014312 (2007)] that were constructed through a complete readjustment rest functional (ii) added perturbatively existing interactions, without readjusting spin-orbit coupling constant. analyze detail mechanisms at play behind how studying latter can help screen out unrealistic parametrizations. It is expected findings present are large extent independent remaining deficiencies central will be great value for construction future, improved functionals.
