The stark realization in recent times that the earth's fossil fuel resources do not represent an inexhaustible supply of fuel to meet society's energy needs has prompted the investigation of many alternative fuel sources. One of these is water splitt

Comparisons of the reflection and diffraction of thermal energy beams of 3He, 4He, H2, and D2 from the (001) surface of LiF are reported. Intense diffracted beams, including those of the second order, result from a freshly cleaved LiF surface without

The scattering of thermal energy atomic and molecular beams from macroscopically rough surfaces has been found to display scattered flux distributions that are typically skewed towards the incoming, beam i.e., backscattered. Such an observation is co

Intensity data for the reflection and diffraction of incident thermal beams of 3 He, 4 He, H 2 , and D 2 from the (001) surface of LiF are presented and compared with a recent theory of diffraction. Particular emphasis is placed on the variation of t

The scattering of thermal energy atomic beams of Ne, Ar, Kr, and Xe from the (001) face of LiF has been studied. Two dominant peaks in the scattering distributions in the plane of incidence are observed: one peak remains fixed with respect to the cry

To date, all experiments concerned with light gas scattering from metal single crystals have failed to show identifiable coherent scattering effects, although strong specular peaks are observed. In the present experiment helium diffraction from the (

The scattering of thermal energy beams of 4He, H2, and D2 from the (111) surfaces of epitaxially grown Ni and Ag single crystals has been measured. Also measured were the angular dependences of the desorption of HD resulting from the dissociation–r

A study of the scattering of thermal energy Ar atoms from the (001) plane of LiF is reported. Multiple peaks in the scattered flux distribution are observed. The major peak in the distribution is the analog of the single lobe directed scattering dist

The equilibrium scattering behaviors of He, H2, and Ar from the cleavage plane of LiF have been measured in order to provide a critical test of the cosine law of total scattering for cases where this result is not the redundant result of Knudsen law
