The influence of quantum electrodynamics (QED) to the process of radiative
electron capture (REC) is investigated in the region of highly relativistic
projectile energies by modifying the wave functions according to the Uehli
ng potential. Exact relativistic calculations are employed for the radiativ
e recombination. The deviation from non-QED calculations is found to amount
to up to 2% in U92+ for a projectile energy of 10 GeV/u and forward emissi
on angles of the emitted photon.
