Abstract
The levels in neutron-rich odd-A Ru-107,Ru-109 nuclei have been investigate d by using gamma-gamma- and gamma-gamma-gamma-coincidence studies of the pr ompt gamma-rays from the spontaneous fission of Cf-252. Th, ground state ba nds and the negative parity bands are identified and expanded in both nucle i. Triaxial rotor plus particle model calculations indicate the ground stat e bands originate from v(d(5/2) + g(7/2)) quasiparticle configurations and the negative parity bands are from vh(11/2) orbital.
