Low-energy electron and positron scattering from C-60: A Progress report on calculations

The scattering of low-energy electrons and positrons From gaseous C-60 mole cules provides much interesting information on the behavior of this molecul e and on the relationship between its structural features and its response to slow electrons and positrons. Our model For these processes has no adjus table parameters and includes both interaction potentials to describe polar ization effects and a non-local exchange potential in the case of electron scattering. These theoretical investigations have allowed us to give a micr oscopic interpretation of observed experimental behavior and has allowed us to propose additional experiments which should exhibit features in both el ectron and positron low-energy collisions which are unique to the C-60 mole cule.
