The confining potential of the He-3@C-60 endofullerene, which consists of a He-3 atom trapped inside a C-60 fullerene cage, is investigated using inelastic neutron scattering. The dynamical structure factor S(Q, omega), which provides information on energy and momentum transfers, is measured and simulated using a spherical anharmonic oscillator model, with good agreement between the experimental and simulated data sets.
The He-3@C-60 endofullerene consists of a single He-3 atom entrapped inside a C-60 fullerene cage. The confining potential, arising from the non-covalent interaction between the enclosed He atom and the C atoms of the cage, is investigated by inelastic neutron scattering. These measurements allow us to obtain information in both energy (omega) and momentum (Q) transfers in the form of the dynamical structure factor S (Q, omega). Simulations of the S (Q, omega) maps are performed for a spherical anharmonic oscillator model. Good agreement between the experimental and simulated data sets is achieved.
