Abstract
The principles of observation of a steady-state interference pattern for th e 2S and 2P levels of hydrogen-like He+ in a uniform electric field are for mulated. A new method for measuring the Lamb shift delta(n=2) = 2S - 2P bas ed on the utilization of the method of atomic interferometer is proposed. Q uantum-electrodynamic consequences that follow from comparing the results o f interferometric measurements and quantum-electrodynamic calculations of t he Lamb shift in He+ are discussed.
