Abstract
Exchange current corrections to the deuteron magnetic and quadrupole moments have been calculated, assuming $ps\ensuremath{-}ps$ theory, employing Tamm-Dancoff formalism, and retaining only up to one-meson amplitudes. The numerical values were estimated by using some reasonable deuteron wave functions. It is shown that the $S\ensuremath{-}D$ cross term is the dominant term and the effect of the change of normalization is always very big, making the whole correction to the deuteron magnetic moment always negative. The relativistic and the nonadditivity corrections to the deuteron moments have also been estimated under the same approximation. The over-all correction to the magnetic moment is shown to be negative and the final estimate of the deuteron $D$-state probability is 3\ifmmode\pm\else\textpm\fi{}1%.
