The exciting opportunities promised by the unique properties of C60 can only be fully exploited if the growth and properties of this material can be understood. To this end we have carried out a study of the structural and vibrational properties of C60 adsorbed on the graphite(0001) surface. We observed a novel high-order periodicity at monolayer coverages which indicates that even the weak corrugation potential of the surface can perturb the geometry of the overlayer. Vibrational spectra show a low-energy resonance in the inelastic scattering cross section which we correlate with a resonance feature observed in the electron attachment cross section of C60. The lack of a measurable perturbation in the resonance upon going from multilayer to monolayer coverage indicates that a weak physisorption bond exists between the molecules and the surface.

Attachment Cross Section

The calculations of the low-energy attachment cross section to metallic clusters are investigated. Low energy electrons are taken as slow enough to excite a giant dipole collective resonance within the cluster. The calculations are more refined than the earlier ones – they do not depend on the experimental data, and we improved RPAE calculation of the collective resonance in the cluster. The results are interesting for the nano-region and designing of new materials.

Scattering Cross

Differential cross sections for elastic scattering and ionization in positron–argon collisions as a function of energy (40–150 eV) are reported at 60°. Of particular interest is the energy range 55–60 eV, where earlier measurements by the Detroit group found a drop in the elastic-scattering cross section of a factor of 2. This structure has been tentatively attributed to a cross channel-coupling effect with an open inelastic-scattering channel, most likely ionization. Our results indicate that ionization remains an important channel over the same energy range and only begins to decrease at an energy above 60 eV.
