Abstract
Using the dielectric theory for a weakly coupled plasma we investigate the stopping power of the ion in a temperature anisotropic magnetized electron plasma. The analysis is based on the assumption that the energy variation of the ion is much less than its kinetic energy. The obtained general expression for stopping power is analyzed for weak and strong magnetic fields (i.e., for the electron cyclotron frequency less than and greater than the plasma frequency), and for low and high ion velocities. It is found that the friction coefficient contains, in addition to the usual velocity independent friction coefficient, an anomulous term which diverges logarithmically as the projectile velocity approaches zero. The physical origin of this anomulous term is the coupling between the cyclotron motion of the electrons and the long-wave length, low-frequency fluctuations produced by the projectile ion.
