Negative parity bands of {sup 115}Pd and band structures in {sup 113,115,117}Pd
Abstract
Level structures of {sup 113,115,117}Pd have been studied using the Gammasphere and a spontaneous fission source of {sup 252}Cf. A new 85.1-keV transition was identified in {sup 113}Pd. This indicates that the spin and parity of the isomeric state is 9/2{sup -} rather than the previously assigned 11/2{sup -}. New low-energy transitions are confirmed in {sup 115,117}Pd. In {sup 115}Pd, the 39.0.- and 49.0-keV transitions are shown to be in prompt coincidence. This coincidence relationship indicates a spin and parity assignment of 1/2{sup +} for the ground state rather than the previously assigned 3/2{sup +}.
