Abstract:
The potential energy surface of 182-186Pt, 184-188Hg, and 186-190Pb in the 4D deformation parameters space (c,ŋ,a3,a4) are evaluated within the macroscopic-microscopic approach using the so-called Fourier-over-Spheroid shape parametrization [1]. The LSD formula [2] is used to evaluate the macroscopic part of the energy, while the microscopic energy correction was obtained using the Yukawa-folded single-particle potential [3]. Pairing correlations are taken within the BCS approximation using an approximate particle-number projection. Each potential energy point at the (β, γ) plane was minimized with respect higher-order deformation parameters (a3 and a4).
A possible shape coexistence and appearance of the shape isomers is discussed.
