Disintegration of Ar N , Kr N , and (N2) N clusters during collisions with highly vibrationally excited SF6 molecules

Abstract

It is shown that, when highly vibrationally excited SF6 molecules (with vibrational energy E vib ≥ 0.5–2 eV) collide with weakly bound van der Waals Ar N , Kr N , or (N2) N (N ≤ 30–40 atoms in a cluster) clusters in intersecting molecular and cluster beams, the molecules are trapped by the clusters, the clusters then undergo full disintegration, and the trapped molecules become free. The method of studying this process and the results obtained are described. The possibilities of application of this method for selective doping of clusters by molecules, laser separation of isotopes, and selective transportation of molecules to a surface are discussed.
