C 105, 034348 (2022) J.Yang, J.Dudek, I.Dedes, A.Baran, D.Curien, A.Gaamouci, A.Gozdz, A.Pedrak, D.Rouvel, H.L.Wang, J.Burkat Exotic shape symmetries around the fourfold octupole magic number N=136: Formulation of experimental identification criteria NUCLEAR STRUCTURE N=122-164; calculated single-particle neutron levelsand Routhians as functions of α30, α31, α32 and α33 octupole deformations; deduced very large neutron shell gaps at N=136 for all the four octupole deformations, and N=136 as a "universal or fourfold octupole magic number". 208,212,216,218Pb, 218,220,222,224Ra, 220Po, 222Rn, 224Ra, 226Th; calculated contours of projections of the total nuclear energy surfaces on (α30, α20) planes for all the isotopes, (α31, α20), (α32, α20), and (α33, α20) planes for 218Pb, (α32, α20) planes for 218,220, 222,224Ra, and (α31, α20) and (α32, α20) planes for 220Po, 222Rn, 224Ra, 226Th. Discussed exotic point-group symmetries C2ν, D2d, Td (tetrahedral symmetry), and D3h in order to formulate spectroscopic criteria for experimental identifications through analysis of collective rotational bands generated by the symmetries. Macroscopic-microscopic method in multidimensional deformation spaces to analyze the expected exotic symmetries and octupole shape instabilities, tetrahedral point group symmetry, and realistic nuclear mean-field theory using phenomenological Woods-Saxon Hamiltonian combined with the Monte Carlo approach. Comparison with available experimental nuclear octupole deformations.
