Proton Rich Nuclei IV

Investigation on the shell evolution far from stability is one of the core tasks of contemporary nuclear physics. Recently the N=82 shell gap at Z=74 obtained in the decay of new isotopes 160Os and 156W [1,2] confirmed theoretical predictions which show robust magicity of the next self-conjugate 164Pb.
Isomers are common in the proximity of N=82, such as the seniority and spin trap isomers in...
Neutron-deficient Pb nuclei feature unique shape coexistence with oblate, prolate and spherical shapes coexisting with few hundred keV in $^{186}$Pb. Not much is known in lighter Pb isotopes, with the spectroscopic knowledge vanishing at $^{178}$Pb. The structure of Pb isotopes with A<186 will allow one to understand the evolution of shape coexistence towards the lighter half of the N=82-126...
