[alpha] and [beta] decays of [sup 169-173]Os and the nuclear structure of the daughter isotopes

The [alpha] and [beta] decays of [sup 169[minus]173]Os were studied using [sup 114]Cd([sup 58]Ni,[ital xn]) and [sup 140]Ce([sup 36]Ar,[ital xn]) reactions. For [sup 169,171]Os new [alpha] rays and [alpha]-coincident [gamma] rays were observed; for [sup 170[minus]173]Os [beta]-delayed [gamma] transitions could be identified for the first time. Evidence for isomeric states in [sup 171,173]Re was found. The nuclear structure in the daughter isotopes is interpreted in terms of single-particle states in the frame of the Nilsson model.
