Abstract: Through measuring high-fold prompt γ- ray coincidence events following the spontaneous fission of 252 Cf with the Gammasphere detector array, new level scheme in the very neutron-rich odd-A 113Ru nucleus has been established. An intruder collective band based on 11/2- level has been identified with spin up to 31/2 k and excitation energy 3.6 MeV. This band most probably originates from vh11/2. intruder orbital. Another collective band probably built on 9/2- level is also observed. Some important characteristics of the collective bands have been systematically discussed.
