Description

The temperature dependences of the energy centroids and strength distributions for Gamow-Teller (GT) 1+ excitations in several fp-shell nuclei are studied. The quasiparticle random phase approximations (QRPA) are extended to describe GT states at finite temperature. A shift to lower energies of the GT+ strength is found, as compared to values obtained at zero temperature. (orig.)
