Abstract
A search for isomeric states was performed in the nucleus using in-beam γ-ray spectroscopy and the (,) reaction. Prompt and delayed γ-ray coincidences were measured with the AFRODITE spectrometer using the pulsed beam delivered by the Separated Sector Cyclotron of iThemba LABS. One new isomer was identified, with spin-parity and lifetime ns, at an excitation energy keV. The lifetime of the isomer at keV was determined to be 32.9(1.8) ns, confirming the previously reported value. The configuration of the isomer is assigned based on configuration-dependent cranked Nilsson-Strutinsky (CNS) calculations as a state , with the spin vectors of the six holes in the core fully aligned.
