Abstract
High-spin states in ${}^{92}\mathrm{Ru}$ were populated via the reaction ${}^{58}\mathrm{Ni}{(}^{40}\mathrm{Ca},\ensuremath{\alpha}2p)$ at 145 MeV beam energy. Using six EUROBALL cluster detectors we measured lifetimes by means of the recoil distance Doppler shift method and are able to propose several significant changes in the published level scheme of ${}^{92}\mathrm{Ru}.$ While the observed spin dependence of $M1\ensuremath{-}$ and moderately enhanced $E2$-strengths is well reproduced by the shell model in the parametrization by Gross and Frenkel, the use of a surface delta residual force leads to less satisfactory results.
