High-spin states in {sup 73}Kr were studied at the XTU tandem accelerator of the Laboratori Nazionali di Legnaro using the reaction {sup 40}Ca({sup 40}Ca,alpha2pn) at a beam energy of 185 MeV. Gamma rays were detected with the EUROBALL spectrometer. Particle detection enabled us to identify the reaction channel leading to {sup 73}Kr. The yrast bands of positive and negative parity were established up to probable spins of 61/2{sup +} and 63/2{sup -}, respectively. The energies of the two identified bands agree well with the predictions of the configuration-dependent Cranked Nilsson-Strutinsky approximation and indicate that the nucleus remains collective up to the maximum spins of the respective high-spin configurations. The positive-parity band represents one of the rare cases where band non-termination at the highest spin of the configuration could be established experimentally.
