The high-spin level structures of the nuclei /sup 95,97/Ru have been studied via the /sup 92/Mo(/sup 6/Li,p2n)/sup 95/Ru and /sup 93/Nb(/sup 7/Li,3n)/sup 97/Ru reactions, using ..gamma..-..gamma.. coincidence, ..gamma..-W(theta), and pulsed-beam-..gamma.. measurements. Shell-model calculations of energy levels and B(E2) values for /sup 95/Ru have been performed and compared with the experimentally observed levels and the measured (21/2)/sup +/ and (17/2)/sup +/ lifetimes. A collective ..delta..J = 2 band has been identified with the 1h/sub 11/2/ neutron state in /sup 97/Ru, and discussed in the context of the general nature of collectivity in nuclei outside the N = 50 closed shell. No ..delta..J = 1 band associated with the 1g/sub 9/2/ neutron-hole intruder state was found in either of the N = 51,53 Ru nuclei, as observed previously for the 1g/sub 9/2/ proton-hole intruder states in the Z = 51 Sb and Z = 53 I nuclei.
