    "abstract": "A method for calculation of Gamow-Teller transition rates is developed by\nusing the concept of the Projected Shell Model (PSM). The shell model basis is\nconstructed by superimposing angular-momentum-projected multi-quasiparticle\nconfigurations, and nuclear wave functions are obtained by digonalizing the\ntwo-body interactions in these projected states. Calculation of transition\nmatrix elements in the PSM framework is discussed in detail, and the effects\ncaused by the Gamow-Teller residual forces and by configuration-mixing are\nstudied. With this method, it may become possible to perform a state-by-state\ncalculation for beta-decay and electron-capture rates in heavy, deformed nuclei\nat finite temperatures. Our first example indicates that, while experimentally\nknown Gamow-Teller transition rates from the ground state of the parent nucleus\nare reproduced, stronger transitions from some low-lying excited states are\npredicted to occur, which may considerably enhance the total decay rates once\nthese nuclei are exposed to hot stellar environments.",
