Following theoretical predictions of competing prolate and oblate potential-energy minima, we present experimental evidence for the coexistence of prolate and oblate nuclear shapes which are associated in a given nucleus with the same single-quasiproton orbital. Prolate {Delta}{ital I}=2 and oblate {Delta}{ital I}=1 bands observed in the {sup 119}I nucleus are proposed as built on an {ital h}{sub 11/2} proton with low {ital K} and high {ital K}, respectively.
