Nuclear structure and decay properties of even-even nuclei in $Z=70-80$ drip-line region

TL;DR

This study investigates the nuclear structure and decay properties of even-even isotopes of elements with atomic numbers 70 to 80 using relativistic mean field theory, comparing results with experimental data and models.

Contribution

It applies the RMF theory with BCS pairing to a wide range of isotopes in the $Z=70-80$ region, providing new insights into shell closures and decay mechanisms.

Findings

Neutron shell closures at N=82 and 126 identified.

Calculated results agree well with experimental data and FRDM.

Probable decay modes of these isotopes analyzed.

Abstract

We study nuclear structure properties for various isotopes of Ytterbium (Yb), Hafnium(Hf), Tungsten(W), Osmium(Os), Platinum(Pt) and Mercury(Hg) in $Z = 70 - 80$ drip-line region starting from $N =80$ to $N=170$ within the formalism of relativistic mean field (RMF) theory. The pairing correlation is taken care by using BCS approach. We compared our results with Finite Range Droplet Model(FRDM) and experimental data and found that the calculated results are in good agreement. Neutron shell closure are obtained at $N=82$ and $126$ in this region. We have also studied probable decay mechanisms of these elements.
