Excited states in the doubly odd nucleus {sup 80}Rb have mainly been studied via the {sup 68}Zn({sup 19}F,{alpha}3{ital n}) reaction at 72 MeV beam energy utilizing the NORDBALL detector system. The level scheme has been extended up to a (15{sup +}) state at 4446 keV excitation energy. In the low-spin region seven new isomers with lifetimes in the nanosecond region have been found. In addition, a 6{sup +} isomer with a half-life of the order of {mu}s has been identified at an excitation energy of 494.4 keV. For the level sequence built on this isomer positive parity is suggested and the states are ascribed to the intruder two-quasiparticle configuration ({pi}{ital g}{sub 9/2}{direct product}{nu}{ital g}{sub 9/2}) and collective excitations.
