Abstract

The level scheme of91Tc has been studied by means of in-beamγ-ray spectroscopy in the irradiations of58Ni and54Fe targets by40Ca beams from the Munich MP tandem and the heavy ion post accelerator. A large number of positive as well as of negative parity yrast-levels with excitation energies up to 8 MeV has been established. The level scheme of91Tc has been compared with shell model claculations and a good agreement for all identified levels has been found.

In parallel investigations of the residual activities of the reaction40Ca→54Fe, theβ decay of the (9/2+ ground) state of91Ru has been investigated. Aβ decay scheme of91Ru(9/2+) has been established. The half-life of91Ru(9/2+) has been measured to be 9±1 s.
