Abstract
An electron beam of 300 keV was directed on to thin target foils (C, Cu, Ag, and Au) to investigate the processes of electron-nucleus bremsstrahlung, electron-electron bremsstrahlung and K-shell ionisation. Using a two-parameter arrangement the outgoing electrons from all these processes were detected in coincidence with the emitted bremsstrahlung and K X-ray photons, respectively, as a function of electron and photon energies for fixed detector angles. So it was possible to measure the triply differential cross sections of the processes of electron-nucleus bremsstrahlung and electron-electron bremsstrahlung and the doubly differential cross section of K-shell ionisation simultaneously. A comparison with theoretical calculations is given.
