Mass spectroscopic confirmation of the presence of C₆₀ in laboratory-produced carbon dust

Krätschmer, Fostiropoulos and Huffman recently suggested that substantial quantities of C60 are present in carbon deposits made by evaporating graphite under 100 Torr He quenching gas. We have directly confirmed the presence of fullerenes in such deposits using a surface-analytical mass-spectroscopic detection technique. © 1990.
