Abstract
We report (e. 2e) measurements at relativistic electron energy (300 keV) on the K shells of silver (E-bind = 25.5 keV) and gold (E-bind = 80 7 keV). U sing coplanar asymmetric kinematics the angular distributions of the relati ve triply differential cross sections were measured. They are compared with results obtained using the relativistic distorted-wave Born approximation. For gold we find that the recoil peak is of the same order of magnitude as the binary peak. This is in good agreement with the theory which predicts a strong increase of projectile-nucleus interaction with increasing atomic number.
