TL;DR

This paper investigates alpha decay half-lives of super-heavy nuclei using theoretical models and experimental data, demonstrating good agreement and providing insights into alpha preformation factors.

Contribution

It introduces a systematic approach to calculate alpha decay half-lives of super-heavy nuclei and compares these with experimental and empirical data.

Findings

Calculated half-lives agree well with experimental data

Alpha preformation factors are derived from theoretical and experimental ratios

The approach shows acceptable accuracy for super-heavy nuclei

Abstract

We considered the systematics of $\alpha$-decay (AD) half-life (HL) of super-heavy nuclei versus the decay energy and the total $\alpha$-kinetic energy. We calculated the HL using the experimental Q_{$\alpha$} values. The computed half-lives are compared with the experimental data and also with the existing empirical estimates and are found in good agreement. Also, we obtained $\alpha$-preformation factors from the ratio between theoretical and experimental results for some super heavy nuclei SHN and evaluated the standard deviation. The results indicate the acceptability of the approach.
