Abstrakt:
Two excited Jpi=O+ states in 186Pb populated in the a-decay of 190Po have been identified
through alpha-particle/conversion electron coincidences in an experiment at the velocity
filter SHIP. The parent l90Po nuclei have been produced in the 142Nd(52Cr,4n)190Po complete
fusion reaction. alpha-particle energies and branching ratios have been measured and
hindrance factors were deduced. The observed states have been interpreted as the band
heads of the known prolate and (yet unobserved) oblate rotational bands in l86Pb.
