The levels of /sup 80/Kr have been investigated using in-beam ..gamma..-spectroscopy techniques via the /sup 70/Zn(/sup 12/C,2n)/sup 80/Kr reaction with 38.4 MeV /sup 12/C ions. The energies, relative intensities, and angular distributions of the g rays were measured. The proposed level scheme shows four bands: three of even parity and one of odd parity. Two-quasiparticle-plus-rotor calculations for /sup 80/Kr suggest that the even-parity band built on the (8/sup +/) state at 3701.6 keV has primarily a proton (g/sub 9/2/)/sup 2/ configuration and the odd-parity band built on the 5/sup -/ state at 2861.0 keV has an essentially pure two-quasiproton (f/sub 5/2/,g/sub 9/2/)5/sup -/ configuration. The observed backbending in the yrast band is attributed to the crossing of the ground band and the excited positive-parity band.
