Erosion and luminescence from pure and impure solid deuterium

Abstract
The first simultaneous measurements of the erosion and luminescence yield from deuterium films bombarded by 2-keV electrons are reported. The luminescence in the region from 200 to 600 nm was measured. A peak at about 275 nm was observed from the solid deuterium. The possible origin of this peak will be discussed. Doping with 0.5% nitrogen changes the luminescence spectrum largely and causes beam-induced evaporation at high current densities.
