Gasdynamic parameters of a supersonic molecular beam seeded by fullerene molecules

Gasdynamic parameters of a molecular beam formed by passing a pulsed beam of a neutral gasthrough a Knudsen cell filled with a fullerene vapor are studied experimentally. It is shown that this method canbe used to advantage in generating supersonic molecular beams of virtually any substances, which is of specialimportance for depositing epitaxial films and films of low-volatility materials.
