The 3/2
- isomer in185 Pb and states above it have been populated in the a-decay of189 Po. The observed a-decay strengths to and the electromagnetic decay properties of the excited states in185 Pb have been combined with Potential Energy Surface and Particle-Plus-Rotor calculations to propose configuration assignments. It is suggested that the a-decaying isomer of189 Po is of prolate origin and that the prolate configuration becomes very low in energy in185 Pb. [ABSTRACT FROM AUTHOR]- Published
