N2 - The problems associated with the formation of an external cluster flow that we previously discovered, which is formed in the external field of a traditional supersonic jet and called the cluster wake, are discussed. The reasons for the long-term anomalous glow of the cluster wake are studied. The results of a spectral study of the induced radiation of a supersonic clustered argon flow in the region of particle excitation (on an electron beam) and beyond are presented. The anomalies in the glow of a traditional spindle-shaped jet and a flow of heavy clusters are discussed. The possible causes of the observed anomalous phenomena are presented based on the above comparisons of the results obtained. The role of the energy exchange between clusters and the background gas in the afterglow of a cluster wake is established. The wavelengths and corresponding transitions in ArI and ArII that are responsible for the anomalous emission are determined. The lifetimes of particles in the excited state in the central part and on the periphery of the clustered flow are determined.
