High spin states in the neutron deficient isotopes [sup 90]Ru and [sup 91]Ru have been studied in the 2[ital p]2[ital n] and 2[ital pn] exit channels of the reaction [sup 36]Ar+[sup 58]Ni using the 149 MeV [sup 36]Ar beam at VICKSI and the OSIRIS array. By gating the [gamma][gamma] coincidences with evaporated neutrons and protons, excited states in [sup 90]Ru were identified for the first time and the level scheme of [sup 91]Ru was extended. In both nuclei, the level energies and branching ratios follow the predictions of shell model calculations performed within the (1[ital g][sub 9/2],2[ital p][sub 1/2]) single-particle space.
