Abstract
Osmium activities of 15-day and 32-hour half-lives have been identified with and , respectively. A 14-hour activity, decaying by a 74.2-kev gamma-transition into the 15-day activity, has been assigned to an isomeric state in . The decay scheme of has been investigated and a 7/2+ assignment has been made to the 15-day ground state and an assignment to the 14-hour isomeric state. The 7/2+ state is attributed to a coupling of an odd number of neutrons.
