Nuclear structure in /sup 95,97/Ru nuclei
- 1. Department of Physics, State University of New York, Stony Brook, New York 11794
Description
The high-spin level structures of the nuclei /sup 95,97/Ru have been studied via the 92Mo(6Li,p2n)95Ru and 93Nb(7Li,3n)97Ru reactions, using γ-γ coincidence, γ-W(theta), and pulsed-beam-γ measurements. Shell-model calculations of energy levels and B(E2) values for 95Ru have been performed and compared with the experimentally observed levels and the measured (21/2)+ and (17/2)+ lifetimes. A collective ΔJ = 2 band has been identified with the 1h/sub 11/2/ neutron state in 97Ru, and discussed in the context of the general nature of collectivity in nuclei outside the N = 50 closed shell. No ΔJ = 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
