The region above /sup 78/Ni would be doubly magic if the numbers Z = 28 and N = 50 retain their magic character far to the neutron-rich side of the stability. We report results of a study of the states in /sup 82/Ge (/sup 78/Ni core+4 protons) and /sup 83/As (/sup 78/Ni core+5 protons) populated in the ..beta../sup -/ decay of /sup 82/Ga and /sup 83/Ge, respectively. Mass separated sources were produced at the TRISTAN separator facility. The measured level schemes were compared to shell-model calculations in which we assume an inert /sup 78/Ni core and extra-core protons that are allowed to fill with minor restrictions all orbits between Z = 28 and 50. The calculations are generally in good agreement with the measurements except for a level in /sup 83/Ge at 711 keV which cannot be easily explained. Finally the degree to which /sup 78/Ni can be considered a valid doubly magic core is discussed.
