Abstract : Structural attributes of calculated surface-rainbow intensity maxima are shown to agree qualitatively with bilobate intensity structure observed in thermal beams of rare gases scattered from single crystal LiF; the scope of correlation encompasses structural variations due to changes in beam energy, angle of incidence, beam specie, and atomic spacing in the azimuth of the incidence plane. These results, which are based on 2D model calculations, imply that mechanisms associated with the bilobate structure differ substantially from those suggested previously. The subject calculations, along with preliminary 3D model calculations, lead to the expectation that a quantitative calculational description of the observed bilobate structure can be obtained.
