Hartree–Fock–Bogoliubov calculation of charge radii of Sn, Ba, Yb and Pb isotopes Original Research Article

Charge radii of Sn, Ba, Yb and Pb isotopes are calculated within Hartree–Fock–Bogoliubov theory with a Skyrme force and a density-dependent delta-force pairing. We investigate mean-field effects of the pairing upon odd–even staggering of isotope shifts. HFB equations are solved in the canonical basis. Odd nuclei are treated in the blocking approximation.
