In obtained mass spectra the most intensive peaks correspond to C60+ ion. At the same time peaks of fragments С58, С56,…С50 are observed, these fragments are formed as a result of stabilization fullerene molecule by cleavage of carbon atoms С2n, n=1,2,..6. During investigation of ions formation dependence on extraction delay, increasing of peaks resolution was observed. Was shown that increasing of extraction delay up to 200 ns correspond to maximal peaks intensity. Such behavior of ions formation is characteristic only for fullerene samples in NMP.
