Excited states in the nuclei super(83)As and super(84,86)Se have been studied via prompt [gamma]-ray spectroscopy. The nuclei were produced by the proton-induced fission of a super(238)U target, at the accelerator of the University of Jyvaskyla. The JUROGAM-II array was used to detect prompt [gamma]-rays and a triple-[gamma] coincidence analysis performed. A comparison of the N = 50 nuclei with shell-model calculations reproduces the low-lying states in 83As and 84Se well. The inclusion of particle-hole excitations is necessary to correctly describe the states above ~ 3.5 MeV.
