EFFECT OF ION-BOMBARDMENT ON X-RAY PHOTOELECTRON-SPECTRA OF AMORPHOUSCARBYNE

X-ray (AlKalpha) photoelectron spectra of valence, core, and Auger ele ctrons for an amorphous carbyne specimen and samples obtained by bomba rding with 1.2-keV argon ions were measured. No argon lines were obser ved in the spectra of irradiated samples. Under given experimental con ditions, irradiation of the starting film with ions for 15 min provide s effective cleaning of its surface from oxygen and fluorine, leaving the dominant type of carbon-carbon bonds virtually unchanged. A half-h our irradiation results in accumulation in a carbyne-like matrix of ca rbon clusters having the sp(2)-hybridization of valence states, which is most profoundly displayed in variation of spectra of satellites to carbon 1s lines.
