Contribution

It introduces a new derivation of super-allowed beta-decay rates in the Coriolis coupling model for mirror nuclei.

Findings

Calculated decay rates match experimental data

Results agree with shell model calculations

Valid for beta-decay between mirror nuclei

Abstract

The expression for super-allowed beta-decay transition rates have been derived within the context of Coriolis coupling model. The derived expressions, valid for the beta-decay between any two mirror nuclei, has been applied to calculate super-allowed beta-decay transition rates of 21Na, 21Mg, 21Al, and 21Si. The calculated rates agree well with the data and the calculations done using the shell model with configuration admixture.
