Excited levels in the decay¹⁸⁵Os→¹⁸⁵Re

Abstract

The energies and intensities of the transitions in the¹⁸⁵Os decay have been determined using Ge(Li) detectors and an iron-yoke double focusing beta-ray spectrometer. Internal conversion measurements performed at a resolution of 0.15% made possible to determine the multipole character of the nine strongest transitions. The proposed decay scheme has been tested by a two parameter coincidence experiment. It has been found that the experimental data agree roughly with the theoretical predictions of Nilsson model description if the Coriolis interaction is taken into account.
