N2 - The results of a spectral study of stimulated emission of a supersonic argon clustered flow in the region of particle excitation (on an electron beam) and beyond it are presented. Anomalies in the glow of a "traditional"spindle-shaped jet and a stream of heavy clusters ("cluster wake") are discussed. Possible mechanisms for initiating the "cluster wake"glow are considered. Possible causes of the observed anomalous phenomena are presented on the basis of the above comparisons of the results obtained. The role of the energy exchange of clusters with the medium in the afterglow of the "cluster wake"is established. The wavelengths and the corresponding transitions in Ar-I and Ar-II, which are responsible for the anomalous emission, are determined. The lifetimes in the excited state of particles in the central part and on the periphery of the clast flow are determined.
