摘要：

Detailed experimental information on high-spin states (up to approximately 20 hBAR) in the N greater-than-or-equal-to 52 nuclei Ru-96, Ru-97, Ru-98 has been obtained from gamma-ray spectroscopic studies following (Cu(S,pxn))-Cu-65-S-36 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 h11/2 neutron configurations.
