Isomeric and high-spin states of Tc94 and the search for yrast isomers near N50

A search for isomers in the N50 region has produced no evidence of high-spin yrast isomerism. A new 4.5-ns low-multiplicity isomer has been identified and assigned to Tc94, while the yrast sequence of Tc94 has been established to more than 5 MeV in excitation energy.
