Abstract
A previous covariant evaluation of the Lamb shift for small atomic numbers is extended to be valid for large and agrees with independent numerical evaluations for near 80. The results improve the precision tests of quantum electrodynamics and could be used for one-electron atoms with any , x rays at large , and superheavy elements with . A substantially new value (due to deuteron size) is found for the deuterium Lamb shift: 1059.27 ± 0.03 MHz.
