The Lamb Shift of Excited S-Levels in Hydrogen and Deuterium Atoms

摘要

A specific combination of $s$-state Lamb shift $\Delta E_L(1s_{1/2}) - = n^3 hydrogen and deuterium atoms for $n$ up to 12. The result inludes all correction which can contribute $1 kHz$ and particulary: one-loop self en= ergy and vacuum polarization, two-loop contribution. Nuclear finite-size corre= ctions for the isotopic difference of the combination are also evaluated.
