Levels of the ground-state cascade of /sup 98/Pd up to J/sup ..pi../ = 16/sup +/ were established by means of the reaction /sup 70/Ge(/sup 32/S,2p2n..gamma..)/sup 98/Pd with E/sub lab/ = 120 MeV. The /sup 96/Ru(/sup 16/O,/sup 14/C)/sup 9/ /sup 8/Pd reaction was used to aid in the nuclidic identification of the observed ..gamma..-ray transitions. We compare the excitation energies of the new states of /sup 98/Pd with states of the N = 52 isotone /sup 96/Ru, which were populated using four distinct reactions. No evidence has been found for the existence of collective four-particle--two-hole states involving the excitation of a pair of g/sub 9/2/ neutrons across the N = 50 shell closure. The level schemes are discussed in terms of the nuclear shell model while the empirical ratios of energies are presented from the viewpoint of the variable moment of inertia model.
