摘要：

The investigation of electron impact ionization by the electron-electron (e, 2e) coincidence technique has until recently been restricted to the non-relativistic energy region (typically 10 eV to 10 keV). We report here on an (e, 2e) experiment using a 500 keV electron beam impinging upon thin-foil targets. Absolute triply differential cross sections and angular distributions for K-shell ionization of silver and gold were measured, showing appreciable discrepancies compared with theoretical predictions.
