Intruder states in very neutron-deficient Hg, Pb and Po nuclei

The gas-filled recoil separator RITU, combined with Ge detector arrays at the Department of Physics, University of Jyväskylä (JYFL), Finland, has successfully been employed in recoil-decay-tagging (RDT) experiments for probing structures of several very neutron-deficient heavy nuclei for the first time. In this paper new data for Hg, Pb and Po nuclei are summarized and discussed. These data shed new light on the behaviour and role of the proton multiparticle-multihole intruder states in nuclei at the 82<N<126 mid-shell and beyond.
