Description

The high-spin spectroscopy of neutron-rich 109Ru is studied by measuring the prompt γ rays from the spontaneous fission fragments of 252Cf with 102 Compton-suppressed Ge detectors in the Gammasphere detector array. Previous band structures are confirmed and the ground state band is extended. A positive parity band based on a 332.5 keV level is newly identified. This band is proposed as a single-neutron excitation band built on the 7/2+[404] Nilsson orbital. Some band structural characteristics are discussed
