    "abstract": "We calculate the contribution of the nucleon-nucleon tensor interaction to\nsingle-particle energies with finite-range $ G $ matrix potentials and with\nzero-range Skyrme potentials. The Skx Skyrme parameters including the\nzero-range tensor terms with strengths calibrated to the finite-range results\nare refitted to nuclear properties. The fit allows the zero-range\nproton-neutron tensor interaction as calibrated to the finite-range potential\nresults and that gives the observed change in the single-particle gap\n$\\epsilon$(h$_{11/2}$)-$\\epsilon$(g$_{7/2}$) going from $^{114}$Sn to\n$^{132}$Sn. However, the experimental $\\ell$ dependence of the spin-orbit\nsplittings in $^{132}$Sn and $^{208}$Pb is not well described when the tensor\nis added, due to a change in the radial dependence of the total spin-orbit\npotential. The gap shift and a good fit to the $\\ell$-dependence can be\nrecovered when the like-particle tensor interaction is opposite in sign to that\nrequired for the $ G $ matrix.",
