Abstract
Two excited J(pi)=0(+) states in Pb-186 populated in the a-decay of Po-190 have been identified through alpha -particle/conversion electron coincidenc es in an experiment at the velocity filter SHIP. The parent Po-190 nuclei h ave been produced in the Nd-142(Cr-52,4n)Po-190 complete fusion reaction, a lpha -particle energies and branching ratios have been measured and hindran ce factors were deduced. The observed states have been interpreted as the b and heads of the known prolate and (yet unobserved) oblate rotational bands in Pb-186.
