Energy spectrum of 116Sn and effective nuclear forces derived from the realistic nucleon-nucleon potentials of Yale and of Tabakin

The effective nuclear forces are obtained by the core polarization renormalization from a realistic local static (Yale) and from a non-local (Tabakin) nucleon-nucleon potential. These forces are applied to the quasiparticle Tamm-Dancoff theory of the spectrum of ¹¹⁶Sn. While the respective bare (unrenormalized) forces lead to different predictions, the renormalized Yale and Tabakin effective forces yield almost identical results. While the second-order core polarization corrections are quite large. the successive inclusion of all the higher-order corrections (iteration) leads to only negligible modifications.
