Stopping of Heavy Ions in Magnetized Strongly Coupled Plasmas: High‐Velocity Limit

Abstract

The energy loss of a heavy ion moving in a magnetized strongly coupled electron plasma is considered within the linear response treatment and in high-velocity regime. The analytical expressions for the stopping power have been found for the arbitrary ion incidence angle. The obtained general expression for the stopping power is analyzed for the ion which moves parallel or perpendicular to the magnetic field. It is found that in general the magnetic field and the Coulomb coupling reduce the stopping power as well as the dynamical screening length at high velocities. The influence of the magnetic field and the Coulomb coupling on the high-velocity stopping power is discussed.

Interactions Between Charged Particles in a Magnetic Field

“…The cut-off s max or its velocity averaged form in (2.59) incorporates the static and dynamic screening effects at low-and high-velocity limits, respectively. It turns out that this dynamic screening length is essentially valid also for the case of magnetized plasma [89,97,113,129], where, however, the magnetic field may play an important role in an intermediate regimes discussed, e.g., in [97] and Sect.

“…Since the early 1960's several theoretical calculations of the SP in a high-velocity regime with the ion velocity v i much higher than the electron thermal velocity v th have been presented in [3,61,88,90,97,122]. Since we assume the high-velocity ion beam the dielectric formalism in linear response becomes accurate.…”
