Abstract
The nucleus has been investigated by -ray spectroscopy using an array of Ge detectors placed at the exit of the fission-fragment mass separator Lohengrin of the Institut Laue-Langevin. New transitions have been identified by studying the decay of . An excitation scheme is proposed and includes a level at 1399 keV and a possible level that are well reproduced by shell model calculations with the most recent parametrization. The properties of the excitations indicate a possible onset of collectivity in .
