Title: Experimental and theoretical Gamow-Teller beta-decay observables for the sd-shell nuclei
Abstract: A comprehensive comparison of experimentally observed Gamow-Teller beta decay with theory is presented for the sd-shell (A = 17–39) nuclei. Relevant experimental data on half-lives, Q values, and branching ratios are tabulated and used to deduce experimental log(ft) values and Gamow-Teller matrix elements. These are compared with theoretical values based on complete (0d52, 1s12, 0d32)-space shell-model wave functions. These wave functions are obtained from diagonalizations of a model Hamiltonian formulation which reproduces observed energy-level structures throughout the sd shell. The calculations are carried out both with the “free-nucleon” normalization for the Gamow-Teller single-particle matrix elements and with effective values for these matrix elements obtained from analyses of experimental Gamow-Teller magnitudes with the shell-model wave functions.
