On Shape Isomers in Hg to Po Region of Nuclei

Abstract : New super and hyper-deformed shapes isomers in even-even Hg to Th isotopes are foreseen [1-5]. The calculation bases on the macroscopic-microscopic model where the macroscopic energy is evaluated using the Lublin-Strasbourg-Drop method and the microscopic, shell plus pairing corrections are calculated with the Yukawa-folded single particle potential. The quadrupole moments and the energies of the lowest rotational state 2+ in all local minima of the potential energy surfaces are evaluated. They are in good agreement with experimental data in the ground states [3,5,6]. The obtained potential energy surfaces explain the main features of the fragment partition as measured in low-energy fission along the isotope chains which lie in a transitional region of the nuclear chart, and shall be essential to consistently understand the evolution of fission properties from neutron-deficient Mercury to heavy actinides. The ability of our method to predict fission observables over such an extended region looks promising.
