Abstract：
Levels in the neutron-rich ¹⁰⁹Ru have been studied by observing the prompt γ-rays following the spontaneous fission fragments of ²⁵²Cf. The ground state band and the negative parity bands have been confirmed and extended. A positive parity band with the band head level at 332.5 keV is newly identified and suggested as a single-neutron excitation band built on the 7/2⁺[404] Nilsson orbital. Some structural characteristics of these bands are discussed.
