Properties of exotic nuclei and their linkage to the nucleonic interaction

TL;DR

This paper explores how the structure of exotic nuclei relates to the underlying nucleonic interactions using self-consistent mean-field theories with semi-realistic interactions, providing insights into nuclear structure far from stability.

Contribution

It develops and applies SCMF calculations with M3Y-type semi-realistic interactions to connect nuclear structure properties with the nucleonic interaction, especially for exotic nuclei.

Findings

Nuclear structure is significantly influenced by the nucleonic interaction.

Semi-realistic M3Y-type interactions effectively describe ground-state properties.

Results extend understanding of nuclei far from stability.

Abstract

The structure of exotic nuclei sheds new light on the linkage of the nuclear structure to the nucleonic interaction. The self-consistent mean-field (SCMF) theories are useful to investigate this linkage, which are applicable to many nuclei covering almost the whole range of the nuclear chart without artificial truncation of model space. For this purpose, it is desired to develop effective interaction for the SCMF calculations well connected to the bare nucleonic interaction. Focusing on ground-state properties, I show results of the SCMF calculations primarily with the M3Y-type semi-realistic interaction, M3Y-P6 and M3Y-P6a to be precise, and discuss in detail how the nucleonic interaction affects structure of nuclei including those far off the $\beta$-stability.
