Mapping the electron–electron interaction in gas phase C₆₀

Abstract

We present a theory for studying the details of the screened electron-electron interaction in fullerenes by means of the coincident electron emission upon charged particle impact. The cross sections for this process are expressed in terms of the screened electron-electron interaction and evaluated within the random-phase approximation. We performed full quantum mechanical calculations for the cross sections and obtained fair agreement with available experiments. Furthermore, we present theoretical angular and energy-resolved cross sections to underline the wealth of information that can be gained by future experiments.

Elastic scattering of intermediate-energy electrons fromC60molecules

“…Much of this attention has been directed toward the C 60 molecule, one of the most basic fullerene structures. Such attention has been primarily directed toward studies of excitation [2][3][4][5], electron attachment [6][7][8][9], and ionization [10][11][12][13][14].…”
