Abstract The levels in neutron-rich odd-A 107,109Ru nuclei have been investigated by using γ -γ -and γ -γ -γ-coincidence studies of the prompt γ-rays from the spontaneous fission of 252Cf. The ground state bands and the negative parity bands are identified and expanded in both nuclei. Triaxial rotor plus particle model calculations indicate the ground state bands originate from v(d5/2+g7/2) quasiparticle configurations and the negative parity bands are from vh11/2 orbital.
