Abstract

High-spin excited states have been identified for the first time in the $N = Z + 1$ nucleus ${}^{89}{Ru}$ with the reaction ${}^{54}{Fe} ({}^{40}{Ca}, α n γ)$ at 130 MeV, using the GASP array, the ISIS Silicon array, and the $n$ -Ring detector system. The observed structure is discussed within systematics of the $N = 45$ isotones and is compared with shell model calculations.
