Effect of short- and long-range correlations on neutron skins of various neutron-rich doubly magic nuclei

TL;DR

This paper investigates how short- and long-range correlations influence neutron skin thickness in neutron-rich doubly magic nuclei, revealing that correlations generally increase neutron skin values.

Contribution

It provides a detailed analysis of the impact of correlations beyond the independent particle model on neutron skin predictions in doubly magic nuclei.

Findings

Correlations tend to increase neutron skin thickness.

Both short- and long-range correlations significantly affect neutron skin calculations.

Results highlight the importance of including correlations for accurate nuclear structure modeling.

Abstract

We study the effects of correlations beyond the independent particle model in the evaluation of neutron skins of various neutron-rich doubly magic nuclei. We consider short- and long-range correlations to take into account the presence of the strongly repulsive core of the bare nucleon-nucleon interaction and collective nuclear phenomena, respectively. Despite the strong sensitivity on the structure of the nucleus considered, our results indicate that, in general, correlations increase the values of the neutron skins.
