    "abstract": "We study the role of the tensor term of the Skyrme effective interactions on\nthe spin-orbit splittings in the N=82 isotones and Z=50 isotopes. The different\nrole of the triplet-even and triplet-odd tensor forces is pointed out by\nanalyzing the spin-orbit splittings in these nuclei. The experimental isospin\ndependence of these splittings cannot be described by Hartree-Fock calculations\nemploying the usual Skyrme parametrizations, but is very well accounted for\nwhen the tensor interaction is introduced. The capability of the Skyrme forces\nto reproduce binding energies and charge radii in heavy nuclei is not destroyed\nby the introduction of the tensor term. Finally, we also discuss the effect of\nthe tensor force on the centroid of the Gamow-Teller states.",
