The energy spectra of 1-3 keV C{sub 60}{sup +} ions reflected from a KCl(001) surface under grazing incidence are measured with an electrostatic spectrometer. Although both nuclear and electronic energy losses are expected to be almost completely suppressed in the grazing scattering of such extremely low energy ions (v{approx}0.01 a.u.) from the wide-band-gap insulator surface, we observe anomalously large energy losses ranging from {approx}25 eV ({theta}{sub i}=1 deg.) to {approx}100 eV ({theta}{sub i}=6 deg.). Fragmentation of C{sub 60}{sup +} ions via sequential C{sub 2} loss is also observed during grazing scattering. We find a strong correlation between the energy loss and the fragmentation. From these results the observed anomalous energy losses are attributed to the internal excitations of C{sub 60}{sup +} ions.
