Properties of superheavy nuclei with Z = 124

TL;DR

This study uses the Relativistic Mean Field model to analyze the properties of superheavy nucleus Z=124, revealing semi-bubble structure and magic neutron numbers at 172, 184, and 198, with comparisons to other models.

Contribution

It provides new insights into the structure and shell gaps of superheavy nuclei Z=124 using RMF with NL3 parametrization, highlighting semi-bubble characteristics.

Findings

Nucleon density at the center is very low, indicating semi-bubble nuclei.

Shell gaps at neutron numbers N=172, 184, and 198 suggest magicity.

Results are compared with the Finite Range Droplet Model.

Abstract

We employ Relativistic Mean Field (RMF) model with NL3 parametrization to investigate the ground state properties of superheavy nucleus, Z = 124. The nuclei selected (from among complete isotopic series) for detailed investigation show that the nucleon density at the center is very low and therefore, these nuclei can be treated as semi-bubble nuclei. The considerable shell gap appears at neutron numbers N = 172, 184 and 198 showing the magicity corresponding to these numbers. The results are compared with the macro-microscopic Finite Range Droplet Model (FRDM) wherever possible.
