The decay of [sup 184]Au to [sup 184]Pt has been studied with mass separated sources from the UNISOR facility. Multiscaled spectra of [gamma]-rays, x-rays and conversion electrons were obtained along with [gamma]-[gamma]-t, and e[sup [minus]]-[gamma]-t coincidence data. The decay scheme of [sup 184]Au to [sup 184]Pt has been updated. In total about 180 [gamma] transitions have been assigned and 52 levels have been established in [sup 184]Pt. Low-energy coexisting bands are identified based on the E0 transitions between states of the same spin in the two coexisting bands. A unique feature of the [sup 184]Pt level scheme is the second set of coexisting rotational bands. The conversion coefficients of [Delta]I = 0 transitions between states of coexisting bands are deduced. In combination with nuclear orientation data, relative E0 strengths are calculated. Results are interpreted in comparison with the theoretical calculation, which predicts that the mixing of coexisting bands gives rise to enhanced E0 transition.
