Cluster Decay Half-Lives of 5d Transition Metal Nuclei Using the Coulomb and Proximity Potential Model

TL;DR

This paper uses the Coulomb and proximity potential model to calculate cluster decay half-lives of 5d transition metal nuclei, finding good agreement with experimental data and identifying more probable decay from heavier isotopes.

Contribution

It applies the Coulomb and proximity potential model to predict cluster decay half-lives of specific 5d transition metal nuclei, providing new theoretical insights.

Findings

Calculated alpha decay half-lives match experimental data.

Heavier isotopes (A=168,180) show higher decay probability.

The model effectively predicts cluster decay behaviors.

Abstract

We have applied the Coulomb and proximity potential model,CPPM to calculate the half lives for various clusters decay of the selected even-even isotopes of the chosen nuclei. These nuclei are Hf, W, Os, Pt, and Hg in the 5d transition metal region in the periodic table with atomic number 72 greater or equal Z less than or equal 80. Furthermore, the half-lives are calculated using the universal formula for cluster decay. The calculated half-lives of alpha decay for the chosen isotopes are in good agreement with the experimental data, especially with the CPPM results. The alpha and cluster decays are more probable from the parents in the heavier mass number A equal 168,180 than from the parents in the lighter mass number A equal 156, 166.
