Abstract
The ejected-electron spectrum of barium vapour between 0 and 20 eV has been observed at 75 degrees to an incident-electron beam of 20-500 eV kinetic energy. A total of 81 lines are reported, corresponding to the radiationless decay of Ba I and Ba II levels. Comparison is made with existing experimental and theoretical data.Keywords
