Abstract

A study of cooled 197Au 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 183,184,186Hf and 186,187Ta. The results support the prediction of a strongly favored isomer region near neutron number 116.
