摘      要：Neutron-de cient nuclei around mid-shell at N-104 in the lead region provide many cases of shape coexistence and shape isomers^([1,2]).In order to study shape coexistence in this region,prompt and delayed-ray spectroscopy of the^(187)Pb,^(183)Hg,^(188)Bi and^(188)Po nuclei produced by the fusion-evaporation reaction^(50)Cr+^(142)Nd→192Po^(*)has been performed at the Argonne Gas-Filled Analyzer.
