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