摘要：

High-spin states in 82Y have been studied by the (Ni(Si,3pn))-Ni-58-Si-28 reaction at 128 MeV. Low-lying states were investigated by the same reaction but at a lower bombarding energy and the band heads of the high-spin sequences have been characterized. Four rotational bands forming two sets of signature partners were established. The yrast band was observed up to J(pi) = 27+ and shows large signature splitting, while a negative-parity yrare band, observed up to spin 22 shows a much smaller splitting. The yrast band structure was very similar to the g9/2 proton band in 79Rb.
