We show that the measurement at high resolution of the kinetic-energy gain spectrum of a highly charged ion (HCI) scattered and partly neutralised by a molecule, a nanocluster or a surface can reveal the excitation spectrum of the target. As a first application of the analysis, we demonstrate that the periodic oscillations in the measured energy gain spectra of energetic Ar q+ ions flying by C60 molecules arise from the coherent multiple excitations of C60 plasmons. © 2010 Elsevier B.V.

Abstract
We show that the measurement at high resolution of the kinetic-energy gain spectrum of a highly charged ion (HCI) scattered and partly neutralised by a molecule, a nanocluster or a surface can reveal the excitation spectrum of the target. As a first application of the analysis, we demonstrate that the periodic oscillations in the measured energy gain spectra of energetic Ar q+ ions flying by C60 molecules arise from the coherent multiple excitations of C60 plasmons. © 2010 Elsevier B.V.
