摘要：

We report here on an (e, 2e) experiment at relativistic electron energies (E0 = 300 keV and 500 keV) in coplanar symmetric geometry. Absolute triple differential cross section measurements for K-shell ionisation of gold, silver and copper are compared with a number of simple first order approximations. Appreciable discrepancies between theory and experiment are found, which reduce with decreasing Z and increasing primary energy. The theoretical calculations show that spin flip effects are important in symmetric geometry, in earlier works these had been neglected.
