Low-energy (5--120 eV) electron-stimulated dissociation of amorphous D {sub 2} O ice: D ({sup 2}{ital S}), O ({sup 3}{ital P}{sub 2, 1, 0}), and O ({sup 1}{ital D}{sub 2}) …

Laser resonance enhanced multiphonon ionization spectroscopy was used to measure
yields and velocity distributions of the D ({sup 2}{ital S}), O ({sup 3}{ital P}{sub 2, 1, 0}), and O
({sup 1}{ital D}{sub 2}) produced during low-energy (5--120 eV) electron-beam irradiation of
amorphous D {sub 2} O ice. Electron-stimulated dissociation has a very low energy
threshold ({similar_to} 6--7 eV), and the neutral fragments desorb with low kinetic energies
({similar_to} 60--85 meV) which are {ital independent} of the incident electron energy. The …

Low-Energy (5–120 eV) Electron-Stimulated Dissociation of Amorphous O Ice: D( ), O( ), and O( ) Yields and Velocity Distributions
GA Kimmel, TM Orlando - Physical review letters, 1995 - APS
Laser resonance enhanced multiphonon ionization spectroscopy was used to measure
yields and velocity distributions of the D (S 2), O (P 2, 1, 0 3), and O (D 2 1) produced during
low-energy (5–120 eV) electron-beam irradiation of amorphous D 2 O ice. Electron-
stimulated dissociation has a very low energy threshold (∼ 6–7 eV), and the neutral
fragments desorb with low kinetic energies (∼ 60–85 meV) which are independent of the
incident electron energy. The data suggest that desorption of neutral fragments results from …
