Abstract
The yrast states in the light platinum isotopes Pt169-173 have been investigated in a recoil-decay tagging experiment using the JUROGAM γ-ray spectrometer in conjunction with the RITU gas-filled recoil separator and the GREAT tagging spectrometer. Gamma-ray transitions have been established for the first time in the odd-N isotopes, Pt169 and Pt173, and the yrast sequences in Pt170 and Pt172 have been extended. We discuss the possibility that the weakly deformed yrast structures of Pt170, Pt172, and Pt173 are crossed by a deformed intruder configuration at spin ∼8.
