Abstract
A possible effect of the low photon density of states in plasma on the Lamb shift is analysed. It is found that because of a significant contribution of high-energy virtual photons to the Lamb shift, its modification in plasma does not exceed 1 % with respect to vacuum even at electron concentrations as high as 1022 cm–3. This behavior results from an asymptotic tendency of plasma properties to vacuum ones at an unlimited frequency growth.
