Abstract

We perform a complete calculation of $\alpha\,(Z\,\alpha)^5\,m$ radiative corrections to the finite nuclear size, the recoil finite size and the nuclear polarizability effects in atomic systems. Results confirm very good agreement for the mean square charge radii difference $r_d^2-r_p^2$ between the deuteron and the proton, as measured in {\em electronic} and muonic isotope shifts.
