Tensor interaction in Hartree--Fock calculations

Abstract

The contribution of the tensor interaction in Hartree-Fock calculations for closed shell nuclei is studied. The investigation is done neglecting the spin-orbit component of the force. As expected from nuclear matter estimates we find that the effect of the tensor interaction is negligible in the case of spin-isospin saturated nuclei and also for medium and heavy nuclei with closed shells. In light nuclei with only one of the two spin- orbit partners filled, such as 12C and 14C, the tensor interaction plays an important role.
