With prompt {gamma}-ray and x-ray spectroscopy on fission fragments, several new transitions in {sup 109,111}Ru have been identified. Angular correlation analysis of several of the new transitions yield evidence of a stretched {ital E}2 band structure. Qualitative Nilsson model arguments, systematics, and triaxial rotor+particle calculations support our hypothesis that the observed band is built on the unique parity {nu}{ital h}{sub 11/2} orbital.
