The positive-parity yrast states in the 89Rb, 92Y, and 93Y nuclei were studied using γ-ray spectroscopy with heavy-ion induced reactions. In the multinucleon transfer reactions 208Pb+90Zr (590 MeV) and 238U+82Se (505 MeV), several γ-ray transitions were identified in these nuclei by means of coincidences between recoiling ions identified with the PRISMA spectrometer and γ rays detected with the CLARA γ-ray array in thin target experiments. Level schemes were subsequently determined from triple-γ coincidences recorded with the GASP array in a thick target experiment, in the reactions produced by a 470 MeV 82Se beam with a 192Os target. The observed level schemes are compared to shell-model calculations
