Abstract：
A method for calculation of Gamow-Teller transition is developed in the framework of the Projected Shell Model (PSM). The shell model wavefunction is the superposition of the angular-momentum-projected multi-quasiparticle configurations. Calculation of transition matrix elements in the PSM is briefly discussed. Our first example indicates that, while experimentally known Gamow-Teller transition rates from the ground state of the parent nucleus are reproduced, stronger transitions from some low-lying excited states are predicted to occur, which may considerably enhance the total decay rates once these nuclei are exposed to hot stellar environments.
