Abstract

The isoscalar magnetic moments and Gamow-Teller

β

decay of the systems

A = 11, 13, 15, 17, 19, and 21

are analyzed in an attempt to extract, in a largely model-independent way, the effective nuclear renormalization of the axial coupling constant:

g_{A} \to g_{Ae}

. We find:

\frac{g_{Ae}}{g_{A}} = 0.920 \pm 0.047

.
