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 (0d/sub 5/2/, 1s/sub 1/2/, 0d/sub 3/2/)- 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 matrix elements obtained from analyses of experimental Gamow-Teller magnitudes with the shell-model wave functions.
