Excited states in the N=90 and N =91 Pt nuclei have been investigated using the JUROGAM and GREAT spectrometers in conjunction with the RITU gas-filled separator. These nuclei were populated via the reactions 92Mo(78 Kr,2n) and 94Mo (78K,3n) at 335 and 348 MeV, respectively. The recoil-decay tagging technique has been used to correlate prompt γ radiation with the characteristic α decays of 168Pt and 169Pt. A γ−γ analysis has allowed a level scheme for 168Pt to be reported for the first time and the level scheme for 169Pt to be extended. The excitation energies of the proposed positive-parity yrast states of 168Pt are compared with calculations based on the interacting boson model and found to be in excellent agreement. These data show a continuation of the trend toward vibrational nuclei as the N=82 shell gap is approached. In addition, new excited states constituting two decay paths have been discovered in 169Pt .
