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.10 pages, 4 figures, 2 tablesNuclear Theorytext
