Nuclear structure corrections in the energy spectra of electronic and muonic deuterium

The one-loop nuclear structure corrections of order (Zα)⁵ to the Lamb shift and hyperfine splitting of deuterium are calculated. The contribution of the deuteron structure effects to the isotope shifts (ep)-(ed) and (μp)-(μd) in the interval $1S--2S$ is obtained on the basis of modern experimental data on the deuteron electromagnetic form factors. Comparison with similar contributions to the Lamb shift for electronic and muonic hydrogen shows that the relative contribution due to the nuclear structure increases on passing from hydrogen to deuterium.
