The non-resonant corrections to the process of the radiative electron capture of highly charged heavy ions

Abstract

The non-resonant (NR) QED corrections to the cascade processes following radiative electron capture by a bare uranium nucleus are considered in connection with the recent measurement of the Lamb shift using electrons from a cooler. Though the calculated values of NR correction are considerably smaller than the experimental accuracy, the analysis shows that the different cascade processes have strongly different dependence on NR corrections. This gives in principle the opportunity to optimize the measurements of the Lamb shift.
