Beta-Decay Coupling Constant and theftValue ofO14

Abstract

A calculation is made of the effect of a charge-dependent internucleon potential on the ${\mathrm{O}}^{14}(0^{+}, T=1)\to {\mathrm{N}}^{14}(0^{+}, T=1)$ $\beta$-decay matrix element. It is found that a not unreasonable strength and form for such a potential can lead to a reduction in the matrix element ≈1% which is of the right order of magnitude to resolve the present discrepancy between the $\beta$- and $\mu$-decay polar vector coupling constants.
