摘要：

The effect of the procedure of preparation of lanthanum-graphite electrodes and the regime of their evaporation in the electric are on the yield of endometallofullerene La@C-82 has been studied. La@C-82 was identified by ESR spectroscopy, optical spectroscopy, and mass spectrometry. The fractional extraction of the fullerene-containing soot with o-xylene makes it possible to separate La@C-82 from higher fullerenes containing no metal atoms and to obtain fullerene extracts enriched in La@C-82.
