Detailed experimental information on high-spin states (up to {approximately} 20 {h_bar}) in the N {ge} 52 nuclei {sup 96,97,98}Ru has been obtained from gamma-ray spectroscopic studies following {sup 65}Cu({sup 36}S,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{sub 11/2} neutron configurations.
