Radiation in the wavelength range 120-900 nm from keV electron bombardment of solid hydrogens

The emission of light from hydrogenic pellet material has been studied in a special experimental set-up. The measurements show that the intensity of light from particle bombarded solid hydrogens is very small and that none of the well known lines for the gas phase are emitted from the solid. The solid hydrogens do not contribute to the strong H-alpha (D-alpha) signal observed from the pellet cloud during penetration into the plasma.
