Abstract
The level structure of92Ru has been studied by means of γ-ray spectroscopy. The nucleus was produced by the58Ni(40Ca, α2p)92Ru reaction at beam energies of 147 and 187 MeV. The NORDBALL detector system including particle selection was used. A large number of new levels with excitation energies up to 11.3 MeV and spin values up to 22 or 23 units of angular momentum have been established. The level scheme is compared with recent shell model calculations using100Sn as a core. Some systematics of the g 2/−29 configuration is discussed and a strong correlation between the levels in90Mo and92Ru is found.
