“…For example, the observed structures above the πh 11/2 isomers in odd-Z Re, Ir and Au isotopes [391,392,393, 394] and the νi 13/2 isomers in odd-N Pt and Hg nuclei [395,396,397,398,399, 400] allowed not only characterization of the structure of the isomers, but also revealed a unique interplay between competing shapecoexisting structures. Prompt radiations were also established above the α-decaying, multi-quasiparticle isomers in 151 Initially, fission tagging was applied in studies of superdeformed isomers in the second well, where a key milestone was the observation of conversion electrons from rotational states above the 4 ns, 240 Pu fission isomer [271,405]. Recent studies by means of α-decay and fission tagging were instrumental in discovering excited structures in very heavy nuclei [285,286,288].…”
