Abstract

We use the shell model Monte Carlo method to calculate complete [Formula Presented]-shell response functions for Gamow-Teller (GT) operators and obtain the corresponding strength distributions using a maximum entropy technique. The approach is validated against direct diagonalization for [Formula Presented]Ti. Calculated GT strength distributions agree well with data from [Formula Presented] and [Formula Presented] reactions for nuclei with [Formula Presented]–64. We also calculate the temperature evolution of the GT[Formula Presented] distributions for representative nuclei and find that the GT[Formula Presented] distributions broaden and the centroids shift to lower energies with increasing temperature.
