Die Zerfälle des Rh97g und des Rh97m

The decays of Rh97g and Rh97m

Abstract

The decays of Rh97g and Rh97m were investigated using Ge(Li)- and Si(Li)-detectors and a Ge(Li)—Ge(Li)-coincidence circuit. The isomeric transition with an energy of 259 keV was identified by its conversion electrons and decays with a half-life of (48.0±0.8) min. Therefore, the half-lives (30.3±0.9) min and (47.9±0.6) min obtained from theγ-studies were attributed to the decays of Rh97g and Rh97m respectively. The proposed decay schemes have 31 excited states of Ru97 and account for 84 of the 110 observedγ-transitions, especially for the 37 strongest ones. Twelve of the proposed levels having spins and parities 1/2− or 3/2− and excitation energies between 2200 keV and 3600 keV are interpreted as being due to 2p 1/2-neutron-hole-states.
