Study of Decay Modes in Transfermium Isotopes

TL;DR

This study employs relativistic mean-field theory to analyze decay modes in transfermium isotopes, predicting decay behaviors and half-lives that align well with experimental data, thus providing new insights into these heavy nuclei.

Contribution

It introduces a comprehensive analysis of multiple decay modes in transfermium nuclei using RMF theory, including weak decay, which is less explored.

Findings

Decay modes predicted match experimental data.

Weak decay half-lives are comparable to other modes.

Most probable decay modes identified across isotopes.

Abstract

In the unknown territory of transfermium nuclei, the relativistic mean-field (RMF) theory has been applied to probe decay modes which include $\alpha$-decay, spontaneous fission (SF), and a less explored weak-decay. These decay modes are analyzed on equal footing for 101$\leq$Z$\leq$109 and as a consequence, the half-lives for weak-decay are indeed found comparable for several isotopes. Our prediction of decay modes and half-lives are found in excellent agreement with available experimental decay modes and half-lives along with the results of some other theories. Out of $\alpha$, $\beta^+$/EC, $\beta^-$, and SF, the most probable decay mode is anticipated along with its half-life over a wide range of odd and even nuclei to frame a novel sight into terra incognita.
