Abstract
The allowed favored beta-transitions are studied in relation to problems of nuclear structure and beta-decay theory. These problems include (1) the influence of deviations from LS coupling on the beta-decay matrix elements of the light nuclei, (2) the relation between the observed magnetic moments, simple nuclear models and deviations from LS coupling, (3) determination of the ratio of Fermi to Gamow-Teller type coupling constants, and (4) determination of the absolute magnitudes of the coupling constants.
