Finite-range simple effective interaction including tensor terms

An existing parametrization of the simple effective interaction (SEI) that is able to reproduce the experimentally known crossing between the 2⁢3/2 and 1⁢5/2 single-particle (s.p.) proton levels in neutron-rich Ni isotopes has been generalized. We have added a short-range tensor force in order to de...
