Super-soft-core nucleon-nucleon interaction with π-, ρ- and gw-exchange contributions

An improved version of the super-soft-core interaction is presented. The known π-, ρ- and gw-exchange contributions are incorporated, while the core and the remainder of the intermediate range are treated phenomenologically. The potential gives a high-quality fit to the two-body bound-state and scattering data up to 350 MeV. The amplitudes are weak in the sense that in nuclear matter, the ratio of second-order to first-order energy perturbations (for the scalar components) are in the region 20–30%. The wound integral κ = 0.077 at kF = 1.4 fm−1. The triplet-even tensor component is weaker than in other phenomenological potentials, but the deuteron form factor is well reproduced. The percentage D-state is 5.92%.
