Modified parameter-sets of M3Y-type semi-realistic nucleon-nucleon interaction for nuclear structure studies

TL;DR

This paper introduces new parameter-sets for the M3Y-type semi-realistic nucleon-nucleon interaction, improving nuclear structure modeling by fully incorporating the interaction's contribution to pairing in mean-field calculations.

Contribution

The study develops modified parameter-sets that account for the entire interaction contribution to pairing, enhancing the applicability of the interaction in nuclear structure calculations.

Findings

Results are consistent with previous models despite the new parameters.

The new parameter-sets do not significantly alter spherical nuclei calculations.

Full inclusion of interaction effects improves the theoretical framework.

Abstract

New parameter-sets of the M3Y-type semi-realistic nucleon-nucleon interaction are obtained, by taking into account the whole contribution of the interaction to the pairing. The interactions are applicable to nuclear structure studies via mean-field calculations and their extensions. Implementing self-consistent mean-field calculations for the spherical nuclei, we confirm that the results do not change significantly from the previous ones, in which the parameters were determined by partly discarding influence of the density-dependent repulsion on the pairing.
