Design and development of a time of flight fast scattering spectrometer : a quantitative surface analysis technique and a new approach towards the experimental investigation of the surface particle interactions
… benefits compared to conventional Low Energy Ion Scattering Spectrometry (LEISS). A major potential advantage arising from the absence of charge exchange complications is the possibility of quantification. The instrumentation that has been developed also offers the possibility of unique studies …

Semiclassical studies of decoherence produced by scattering
The conventional notion of coherent atom-surface scattering originates from the existence of Bragg peaks in elastic scattering. The helium atom acts as a quantum mechanical matter wave that is coherent with itself; the well-defined phase relationship of the particle beam at the different spatial …

Extremal effects in rotationally inelastic diffraction
The scattering of the hydrogenic molecules H2, D2, and HD from vacuum cleaved MgO (001) along the [110] azimuth has been studied. A thermal beam at 300 K and 80 K was used. Particular emphasis has been placed on the rotational inelastic processes which accompany diffraction of RD. Singularities in …
