Elastic electron scattering from CH3I molecules oriented in the gas phase
- 1. Fakultaet fuer Physik, Universitaet Bielefeld, D-4800 Bielefeld 1 (Germany)
Description
A novel experiment on elastic electron scattering from free, spatially oriented molecules has been performed. CH3I molecules state selected by an electrostatic hexapole lens were oriented in a homogeneous electric field. The differential scattering cross sections were measured at an electron energy of 1 keV in the angular range of 4 degree--14 degree with the orientation switched on and off. From these data the orientation-dependent contribution to the molecular interference was determined. The results show a distinct oscillatory pattern as a function of momentum transfer as predicted by theory
