Abstract
Secondary electron emission under deuteron bombardment at normal incidence over the energy range 50–170 keV was measured for scandium and erbium metals and their deuterides. Electron yields reported for the metals were taken from surfaces shown by in situ Auger spectroscopy to have a minimum amount of contamination. The secondary ratio at 100 keV was measured to be 1.30±0.05 for scandium and 1.43±0.05 for erbium. Emission coefficients for the deuterides were measured after a moderate vacuum bakeout and are significantly higher than for the metals.
