Abstract
Excited states of the proton-unbound nucleus 177Au have been populated following the 92Mo(88Sr,2pn) reaction in an experiment performed at the University of Jyv�askyl�a Accelerator Laboratory. Gamma rays detected in the JUROGAM spectrometer were correlated with the characteristic � decays of 177Au detected following a recoil implantation in the GREAT spectrometer. A large number of transitions (� 60 rays) have been assigned unambiguously to 177Au and ordered into four collective band structures and other singleparticle excitations. Several intruder con�gurations formed by single-proton excitations across the Z = 82 shell gap have been established. These have been interpreted as �i13=2, �f7=2 � h9=2 and �h9=2 prolate con�gurations. It has been established that the �i13=2 and �f7=2 �h9=2 bands have decay paths to both the positive-parity mixed (1/2+� 3/2+) ground state and the negative-parity 11/2
