Origin of molecular orbital splitting of C60 on Al(110)

We have investigated the C60 monolayer on Al(110) with angle-dependent photoelectron spectroscopy. We find that orbital components have different angular distributions.

Description
Summary:We have investigated the C60 monolayer on Al(110) with angle-dependent photoelectron spectroscopy. We find that orbital components have different angular distributions. Calculations of cross sections of the highest occupied molecular orbital components for free, oriented C60 are found to describe the experimental data quite well. The observed band splitting is attributed to intramolecular electronic correlations, due to the different coupling of the orbital components to the substrate conduction band.
