Abstract

We consider the effective interaction between electrons owing to the exchange of virtual acoustic waves in a low-temperature plasma. Electrons are supposed to participate in rapid radial oscillations, forming a spherically symmetric plasma structure. We show that under certain conditions, this effective interaction can result in the attraction between oscillating electrons and can be important for the dynamics of a plasmoid. Some possible applications of the obtained results to the theory of natural long-lived plasma structures are also discussed.
