Description
Summary:The ground state properties of Ds （Z=110） isotopes （N=151-195） are studied in the framework of the relativistic mean field （RMF） theory with the effective interaction NL-Z2.The pairing correlation is treated within the conventional BCS approximation.The calculated binding energies are consistent with the results from finite-range droplet model （FRDM） and Macroscopic-microscopic method （MMM）.The quadrupole deformation,α-decay energy,α-decay half-live,charge radius,two-neutron separation energy and single-particle spectra are analyzed for Ds isotopes to find new characteristics of superheavy nuclei （SHN）.Among the calculated results it is rather distinct that the isotopic shift appears evidently at neutron number N=184.
