摘要
Relative elastic differential cross sections for scattering of 1 keV electrons from CF3H, CF4, CF3Cl, CH3F and CH3Cl molecules were measured for momentum transfer from 3 angstrom-1 to 29 angstrom-1. The oscillatory residuals remaining after substraction of the atomic scattering and the molecular interference contributions calculated in the independent atom model are ascribed to the influence of intramolecular multiple scattering. The data reflect the dominant contributions of the CF3-group and show larger oscillations than obtained from triple scattering calculations according to the method of Liu and Bonham using the second Born approximation.
