Elastic scattering of intermediate-energy electrons from C-60 molecules

摘要

Experimental and calculated differential cross sections for elastic scattering of electrons by C60 molecules at collision energies of 100 to 500 eV are reported. The elastic differential cross sections were measured in a standard crossed-beam apparatus, while the calculations were performed employing the Schwinger multichannel technique at the static-exchange level. Diffraction effects, some due to the overall spherical-cage structure and some to scattering by individual C atoms, are observed in both the measured and calculated cross sections.
