✦ Synopsis

The relation between VUV radiation spectra of argon and krypton supersonic jets excited by an electron beam and the mean size of clusters in a jet is studied. For each atomic and molecular emission of argon in the 104-120 nm range and of krypton from 116 to 130 nm, the maximum intensity is found to occur when electrons collide with clusters of a definite mean size. It is found that self-localized excitons of atomic type or diatomic excimer molecular type with a small binding energy (several hundredths of an eV) are mainly formed in outer icosahedral shells of argon or krypton clusters and those of diatomic excimer molecular type with a large binding energy (several tenths of an eV) arise principally in inner shells.
