Doping mechanism of C60 fullerene by sodium and potassium

ESR spectra of localized states of KC₆₀ and K₂C₆₀ and conducting electrons of K₃C₆₀ were recorded in the process of doping C₆₀ by potassium. The ESR spectra of K _x C₆₀ (x < 3) and Na _x C₆₀ correspond to the semiconductive state of the samples.Translated fromIzvestiya Akademii Nauk.
