In recent years, several cases of nuclei presenting the so-called "B-4/2 anomaly" have been observed in the neutron-deficient region close to Z = 50 and Z = 82. In the last region, the osmium isotopic chain is of particular interest, as three consecutive isotopes, 168,169,170Os, have shown the presence of this peculiar phenomenon. An experiment aimed at extending the study to Os-167 was performed at the Accelerator Laboratory of the University of Jyvaskyla, using a beam of 78Kr at 360 MeV impinging on a Mo-92 target. Lifetimes of several low-lying states were measured using the Recoil-Distance Doppler Shift method. The preliminary analysis and the study of the influence of unobserved feeders are discussed.
