Abstract

Equations describing evolution of the velocity of a rarefied ion beam in a plasma with ion-acoustic turbulence are derived and solved. An ion beam with velocity u greater than the sound speed v_{s} decelerates due to Cherenkov radiation of ion-acoustic waves. Conversely, a beam with u

期刊介绍： Physical Review E (PRE), broad and interdisciplinary in scope, focuses on collective phenomena of many-body systems, with statistical physics and nonlinear dynamics as the central themes of the journal. Physical Review E publishes recent developments in biological and soft matter physics including granular materials, colloids, complex fluids, liquid crystals, and polymers. The journal covers fluid dynamics and plasma physics and includes sections on computational and interdisciplinary physics, for example, complex networks.
