Gamow-Teller beta-decay rates for A <= 18 nuclei

A comprehensive analysis is made of the experimental information on Gamow-Teller beta decay for the light ([ital A][le]18) nuclei. Experimental data on half-lives, [ital Q] values, and branching ratios are tabulated. Experimental log[ital ft] values and beta-decay matrix elements are deduced from these data. The one-body-transition densities necessary to predict the beta-decay matrix elements are then calculated using a recently constructed shell-model Hamiltonian operating in the first four major shells. Using these parameters, effective Gamow-Teller operators are deduced for the 0[ital p] shell from a least-squares fit to 16 experimental matrix elements. The effective operators are used to calculate 83 decay matrix elements. Some specific decays are discussed.
