Measured E2 and M4 transitions and energy levels in the N = 50 isotones with Z> 38 are satisfactorily reproduced by a shell model with proton configurations (2p/sub 1/2/, lg/sub 9/2/)/sup n/. Four sets of twobody matrix elements are found by least-squares fitting to energy levels and transition rates in the N = 50 isotones. These interactions include one that exactly conserves seniority and another that fits the strongly inhibited 8+ yields 6+ transition in /sup 94/Ru. Slight seniority nonconservation is required to predict inhibited N = 50 transition rates. The sign of the off-diagonal matrix element is determined by comparison with experimental M4 rates. The seniority conserving interaction is found to be equivalent to the best seniority nonconserving interaction for prediction of energy levels. (auth)
