The ejected-electron spectrum of Ag I autoionising transitions resulting from 20-400 eV electron impact excitation

The ejected-electron spectrum of silver vapour atoms has been observed at 75 degrees with respect to an incident electron beam of 20-400 eV kinetic energy. A total of 82 lines are reported corresponding to autoionisation in Ag I. Where possible assignments have been made based on available theoretical and experimental data. Hartree-Fock calculations are reported for the 4d 9 5p 2 configuration.
