Abstract
The matrix elements of the effective Hamiltonian in the 0g_9/2-1p_1/2 space are determined by a least-square fit to the energies of 477 levels of nuclei with $38\le Z \le 50$ and $47 \le N \le 50$ . The results of the calculation are found to be in better agreement with experiment than those obtained with previously determined interactions.
