Abstract
A study of cooled (197)Au projectile-fragmentation products has been performed with a storage ring. This has enabled metastable nuclear excitations with energies up to 3 MeV, and half-lives extending to minutes or longer, to be identified in the neutron-rich nuclides (183,184,186)Hf and (186,187)Ta. The results support the prediction of a strongly favored isomer region near neutron number 116.
