Excited states in {sup 107}Mo, populated in spontaneous fission of {sup 248}Cm, were studied by use of the eurogam2 multidetector array. Spins and parities of the ground state and the 66.0-, 152.1-, and 458.5-keV excited levels, reported previously, were changed based on conversion-coefficient and angular-correlation measurements. Octupole deformation reported previously in {sup 107}Mo is dismissed, and we explain the near-yrast structure of {sup 107}Mo in terms of rotational bands built on the 5/2{sup +}[413], 3/2{sup +}[411], and 7/2{sup -}[523] orbitals.
