Elastic scattering of intermediate-energy electrons from C60 molecules
نویسندگان
چکیده
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.

Crossed-beam experiment for the scattering of low- and intermediate-energy electrons from BF3: A comparative study with XF3 (X = C, N, and CH) molecules.
Absolute differential cross sections (DCSs) for electron interaction with BF3 molecules have been measured in the impact energy range of 1.5-200 eV and recorded over a scattering angle range of 15°-150°. These angular distributions have been normalized by reference to the elastic DCSs of the He atom and integrated by employing a modified phase shift analysis procedure to generate integral cross...

متن کاملElastic scattering and impact ionization by returning electrons induced in a strong laser field
We study elastic scattering and impact ionization by returning electrons induced in a strong laser field based on the recently developed quantitative rescattering theory. The high-energy angle-resolved photoelectron spectra of molecules in strong fields are attributed to elastic scattering of the returning electrons with the parent ion. We demonstrate that the high-energy photoelectron spectra ...
متن کاملQuasi-elastic scattering of electrons at large momentum transfer
Precision measurements of the energy of keV electrons scattered ‘elastically’ over large angles from solid films or gas-phase molecules show that these electrons have lost some energy. In particular scattering from a system that contains hydrogen and carbon reveals two well-separated elastic peaks. The amount of energy lost in the deflection of the electron depends not only on the mass of the n...
