Standard shell-model techniques of constructing and diagonalizing Hamiltonians in finite Hilbert spaces have been used to treat the N = 50 isotones with an expanded model space and a new empirical effective interaction. A vector space with active 0f/sub 5/2, 1p/sub 3/2, 1p/sub 1/2, and 0g/sub 9/2 proton orbits is used to model the low-lying excitations of these nuclei. The effective interaction is obtained by varying 35 parameters, distributed over the 65 two-body matrix elements and four single particle energies of the model space, to fit over 170 experimental energy levels in nuclei from /sup 82/Ge through /sup 96/Pd. Nearly all of the experimental level energies of N = 50 nuclei involved in the fit are well reproduced by the final interaction
