Evolution of nuclear shapes in medium mass isotopes from a microscopic perspective

The self-consistent Hartree-Fock-Bogoliubov approximation based on the finite-range and density-dependent Gogny interaction (parametrization D1S) has been used to generate potential energy curves in various chains of Pd, Xe, Ba, Nd, Sm, Gd, and Dy isotopes. The evolution of shapes with the number of nucleons is studied and a search for signatures of E(5) and X(5) critical point symmetries is also conducted. The results are compared with those obtained in the framework of other mean-field approximations to the nuclear many-body problem. The role of triaxiality in nuclei where this degree of freedom could be relevant is considered and discussed.

“…Several candidates have already been proposed experimentally for both E(5) and X(5) symmetries. For example, the nuclei 134 Ba [7], 102 Pd [8], 108 Pd [9], and 128−130 Xe [10] have been identified as candidates for E(5), whereas 152 Sm [11], 150 Nd [12], 154 Gd [13], and 156 Dy [14] provide examples of X(5) symmetry.…”

“…As shown in [29], there are many nuclei in A = 100-130 mass region near the E(5) critical point. It was confirmed in [9] that 102 Pd, 104 Ru, and 116 Cd are good candidates near the E(5) critical point.…”

A solvable extended Hamiltonian that includes multi-pair interactions among s-and d-bosons up to infinite order within the framework of the interacting boson model is proposed to gain a better description of E(5) model results for finite-N systems. Numerical fits to low-lying energy levels and reduced E2 transition rates within this extended version of the theory are presented for various N values. It shows that the extended Hamiltonian within the IBM provides a better description of the E(5) model results for small N cases, while the results of the model in the large-N cases are close to those of the E(5)-β 2n type models studied previously.

“…The stable isotopes of xenon span a region which exhibits such an evolution of nuclear structure, and in a literature search for other E(5) candidates, Clark et al, proposed 128 Xe as the best prospect [3]. This conclusion was based on several criteria: the ratio E(4 Following this supposition, the structure of 128 Xe was investigated using Coulomb excitation [4].…”

Abstract. Highly enriched (> 99.9%) 132 Xe and 134 Xe gases were converted to solid 132 XeF 2 and 134 XeF 2 and were used as scattering samples for inelastic neutron scattering measurements at the University of Kentucky Accelerator Laboratory (UKAL). Lifetimes of levels up to 3.5 MeV in excitation energy in these xenon isotopes were measured using the Doppler-shift attenuation method, allowing the determination of reduced transition probabilities. Gamma rays corresponding to new transitions and levels have been observed. In particular, tentative new excited 0 + states and associated decays have been examined in an effort to elucidate the structure of these nuclei in a transitional region, and comparisons have been drawn with models which seek to describe such nuclei, e.g., the E(5) critical-point symmetry of the IBM. Newly identified potential interferences for neutrinoless double-beta decay searches involving 136 Xe are also discussed.
