The nucleus $^{74}\mathrm{Kr}$ has been populated in the $^{40}\mathrm{Ca}$($^{40}\mathrm{Ca}$,$2p\ensuremath{\alpha}$)$^{74}\mathrm{Kr}$ fusion-evaporation reaction at a beam energy of 165 MeV and studied using the Gammasphere and Microball multidetector arrays. The lifetimes for low-spin states in the ground-state and two signature-split negative-parity bands were determined using the Doppler-shift attenuation method. These results are discussed together with the lifetimes measured for the high-spin states of these bands and compared with theoretical calculations.
