Collective plasmon excitations inC60clusters
Abstract
The electromagnetic response function of a ${\mathrm{C}}_{60}$ cluster is calculated using linear-response theory. We find that the valence electrons are quite delocalized and show collective excitations. In the low-energy part of the excitation spectrum, the lowest allowed transition at \ensuremath{\Elzxh}\ensuremath{\omega}\ensuremath{\approxeq}3 eV is strongly screened, and the other transitions below 6 eV are moderately screened, in agreement with experiment. We also predict a giant collective resonance at an unusually high energy of \ensuremath{\approxeq}20 eV.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
