High-spin states in the nucleus Ru102 have been investigated via the Zr96(C13,α3n) reaction at beam energies of 51 and 58 MeV, using the euroball IV γ-ray spectrometer and the diamant charged particle array. Several new high-spin bands have been established. The ground-state band has been extended up to Ex~12 MeV with Iπ=(26+); the previously published negative-parity bands have been extended up to Ex~11 and ∼ 9 MeV with Iπ=(23-) and (20-), respectively. The deduced high-spin structure has been compared with Woods-Saxon total Routhian surface calculations and, on the basis of the measured Routhians, aligned angular momenta, and B(M1)/B(E2) ratios, νh11/2(g7/2,d5/2) configurations are suggested for the negative-parity structures.
