### Abstract

We use the shell model Monte Carlo method to calculate complete 0f1 p-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 ^{48}Ti. Calculated GT strength distributions agree well with data from (n,p) and (p,n) reactions for nuclei with A=48-64. We also calculate the temperature evolution of the GT_{+} distributions for representative nuclei and find that the GT_{+} distributions broaden and the centroids shift to lower energies with increasing temperature.
