Abstract: | Auger spectra of thin fullerite (C60) films have been measured under the conditions precluding their electrostatic charging and destruction. The Auger line of
these subjects, E
f=268.3±0.2 eV, turned out to lie considerably lower in energy than that of the ion-beam amorphized graphite (E
AG=272.3±0.2 eV) and of pyrographite (E
PG=271.8±0.5 eV). Fullerite was found to convert to a graphitic form under irradiation by low-intensity electron beams used
customarily in AES, reflection EELS, and inverse photoemission spectroscopy. It has been established that such beams produce
noticeable changes in the fullerite structure already in a few minutes of irradiation.
