Abstract
Excited states in the proton-unbound Au-173,Au-175,Au-177 nuclei were ident ified for the first time. Level structures associated with three different shapes were observed in Au-175. While the yrast lines of Au-175 and Au-177 consist of a prolate band built upon the intruder 1/2(+) [660] (i(13/2)) pr oton orbital, no sign of collectivity was observed in the lighter Au-173 is otope, Implications for the deformation associated with these structures ar e discussed with a focus on shape co-existence in the vicinity of the proto n-drip line.
