Transitions in the very neutron-deficient isotope[sup 186]Pb have been identified in mass-gated, recoil-[gamma], and recoil-[gamma]-[gamma] coincidence data obtained with a fragment mass analyzer and Compton-suppressed Ge-detector array. The results of the present work confirm and extend a band of levels tentatively proposed in earlier work done elsewhere, and provide a definitive mass assignment of the observed transitions. The band observed in [sup 186]Pb bears a very close resemblance to the yrast band in the isotone [sup 184]Hg, supporting the view that the [sup 186]Pb band is built upon a prolate structure.
