Superdeformed and Hyperdeformed States in Z=122 Isotopes
Abstract
We calculate the binding energy, root-mean-square radius and quadrupole deformation parameter for the recent, possibly discovered superheavey element Z=122, using the axially deformed relativistic mean field (RMF) and non-relativistic Skyrme Hartree-Fock (SHF) formalisms. The calculation is extended to include various isotopes of Z=122 element, strarting from A=282 to A=320. We predict highly deformed structures in the ground state for all the isotopes. A shape transition appears at about A=290 from a highly oblate to a large prolate shape, which may be considered as the superdeformed and hyperdeformed structures of Z=122 nucleus in the mean field approaches. The most stable isotope (largest binding energy per nucleon) is found to be 122, instead of the experimentally observed 122.
