Abstract

Isomeric states in Tc-112 and Tc-113, with half-lives of 150(17) ns and 500(100) ns, respectively, have been observed following the relativistic fission of U-238. The fission fragments have been separated in a fragment separator and identified by means of energy-loss and time-of-flight techniques. In both nuclei, the ground-state configuration is calculated to have an oblate shape and the isomerism is proposed to arise due to transitions from a triaxial excited state to a low-lying oblate state.
