Abstract: Through measuring prompt γ-rays emitted in the spontaneous fission of 252Cf with higher statistic data,level structures in the neutron rich,odd A107Ru nucleus have been re investigated. New level scheme of 107Ru has been established. The ground state band was extended with spin up to 27 2h. The νh11/2 band structure observed in our previous publication has been confirmed and extended. These results clear up the inconsistence between our earlier work and results from another experiment published recently. A collective band built on (9/2-) level has been observed for the first time. Some important features of the level scheme have been discussed.
