Abstract

Lifetimes of high-spin states have been measured in the semi-magic (N= 50) nucleus ⁹⁴Ru. Excited states in ⁹⁴Ru were populated in the ⁵⁸Ni(⁴⁰Ca, 4p)⁹⁴Ru^* fusion-evaporation reaction at the Grand Accélérateur National d’Ions Lourds (GANIL) accelerator complex. DSAM lifetime analysis was performed on the Doppler broadened line shapes in energy spectra obtained from γ-rays emitted while the residual nuclei were slowing down in a thick 6mg/cm^2 metallic ⁵⁸Ni target. In total eight excited-state lifetimes in the angular momentum range I= (13 - 20) ℏ have been measured, five of which were determined for the first time. The corresponding B(M1) and B(E2) reduced transition strengths are discussed within the framework of large-scale shell model calculations to study the contribution of different particle-hole configurations, in particular for analyzing contributions from core-excited configurations.
