Description
The lifetimes of the high-spin states in the semi-magic (N=50) nucleus $^{94}\mathrm{Ru}$ have been determined using the Doppler Shift Attenuation Method (DSAM). Excited states in $^{94}\mathrm{Ru}$ nucleus were populated via $^{58}\mathrm{Ni}(^{40}\mathrm{Ca},4p)^{94}\mathrm{Ru}^*$ fusion-evaporation reaction at the GANIL accelerator complex. DSAM lifetime analysis was performed on the Doppler broadened line shapes in energy spectra obtained from the emission of $\gamma$-rays while the residual nuclei were slowing down in the thick ($6~mg/cm^2$) metallic $^{58}\mathrm{Ni}$ target. The lifetime results have been validated with respect to the previous measurements and totally eight excited-state lifetimes have been obtained. Large-scale shell model calculations have been carried out and compared with experimental results.
