Gamow-Teller distributions in nuclei with mass A=92-97

In many applications a nuclear model able to describe both the low-energy spectra and Gamow-Teller strength distribution is desirable. The model of choice is shell model diagonalization approach, which, however, requires to solve a large dimension eigenvalue problem. Current tasks are both time- and memory-consuming, and one of the ways to overcome this difficulty is to have a parallel computer code. I will talk about efforts to have such a code at Oak Ridge National Laboratory, and show recent results on Gamow-Teller calculations for nuclei with mass A=92-97 assuming Sr88 as a closed core and using a realistic interaction derived from G-matrix.
