Abstract
The bremsstrahlung process in the domain of strong Coulomb fields has been investigated for N-2 and Ar target electrons colliding with He-li ke uranium ions at 223 MeV/u. The differential cross sections for brem sstrahlung were measured at laboratory observation angles of 48 degree s, 90 degrees, and 132 degrees. Substantial discrepancies were found b etween the experimental cross sections and the first-order Born approx imation calculations. The reported data provide a new testing ground f or non-perturbative treatment of the coupling between radiation and ma tter in the presence of strong fields.
