    Notes: Beams of Ne and Ar of energy 63 meV are diffracted by LiF(100) at 294 K and then passed through a velocity selector (resolution 3%) set to transmit only the nearly elastic scattering. This amounts to fractions 0.13 and 0.054, respectively, of the total scattering reaching the detector when the selector is removed. The clearly resolved structure in the angular distributions of these relatively heavy atoms scattered from the surface may provide useful information about the potential for these systems. A simplified analysis yields an estimate for the corrugation parameter for Ar+LiF(100).

    Notes: The basic theory of X-ray scattering is applied to various hypothetical models for the bulk state of block polymers in order to explain the angular dependent scattering. The intensity of scattering is calculated for a rnicellar model, a zone model, and a molecular dumbbell model. The molecular dumbbell model, in contrast to the micellar and zone models, assumes that a block copolymer containing domains may be treated as one giant molecule and that, therefore, the locations of the domains are not random but are governed by the statistics of the segments which interconnect them. Experimental and calculated scattering curves are compared for several different types of block polymers.
