Abstract
In the relativistic quantum mean field theory retardation effects are investigated for spherical nuclei throughout the Periodic Table. In a Hartree-Fock calculation retardation affects only the exchange terms; the exchange of {sigma}, {omega}, {rho}, and {pi} mesons and photons are included. We find the retardation is important only for the pion; for the other heavier mesons its contribution is negligibly small. The total binding energy of a nucleus can be changed by about 5% when retardation is included. For the electric charge density appreciable difference is observed only for {sup 208}Pb.
