Abstract

The 390-kev $γ$ -line reported to be associated with ${Tc}^{92}$ is found to be ${Tc}^{93}$ and is shown to be a $M 4$ isomeric transition. Mass assignment to ${Tc}^{96}$ is made for the isomeric transition previously known to have 34.4-kev energy and 51.5-minute half-life, and a weak positron branching was found.
