Abstract

The lifetimes of the high-spin states in ¹⁷⁴Os have been measured with the recoil distance technique. The extracted transition quadrupole moments of the yrast levels are essentially constant (≈7.7 e b) up to spin 20⁺. Although this behaviour differs from that observed in the neighbouring even-even N = 98 isotone ¹⁷²W, it does not, at present, preclude the possibility of a h_{9 2} proton alignment in these nuclei.
