THE NONRESONANT CORRECTIONS TO THE PROCESS OF THE RADIATIVE ELECTRON-CAPTURE OF HIGHLY-CHARGED HEAVY-IONS

The non-resonant (NR) QED corrections to the cascade processes followi ng radiative electron capture by a bare uranium nucleus are considered in connection with the recent measurement of the Lamb shift using ele ctrons from a cooler. Though the calculated values of NR correction ar e considerably smaller than the experimental accuracy, the analysis sh ows that the different cascade processes have strongly different depen dence on NR corrections. This gives in principle the opportunity to op timize the measurements of the Lamb shift.
