Neutron measurements of intramolecular vibrational modes inC60

Abstract

Neutron-inelastic-scattering measurements have been made on a sample of highly purified solid ${\mathrm{C}}_{60}$. New features in the spectrum of intramolecular modes not obtainable by optical spectroscopy have been identified. Available theoretical calculations show trends in accord with the experimental results but disagree in important details, and improved calculations are desirable.
