Abstract

The high spin yrast structure of

{}^{117}I

has been studied with the

{}^{27}{Al}

+^{94}

Mo reaction at 129 MeV. Three structural features have been identified: (i) coexisting prolate (γ=0°) and oblate (γ=-60°) collective shapes involving the π

h_{11 / 2}

orbital, (ii) noncollective oblate (γ=+60°) shapes associated with band termination, and (iii) a delayed ν

h_{11 / 2}

crossing frequency in the π[550]1/

2^{-}

yrast band.
