Detailed experimental information on high-spin states (up to ~ 20 ft) in the N ≥ 52 nuclei 96,97,98Ru has been obtained from gamma-ray spectroscopic studies following 65Cu(36S,pxn) reactions. The level schemes exhibit sequences of presumably negative-parity states linked by E2 transitions with monotonously increasing energies. These sequences coexist with the positive-parity yrast states where the transition energies are rather irregular. The negative-parity structures are suggestive of the emergence of rotational collectivity. The data are compared with TRS calculations for deformed h 11 2 neutron configurations.
