Abstract

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