Relaxation of charged particles injected into a hot plasma
Abstract
Relaxation ranges and times of charged particles injected into a hot plasma are derived and compared with classical theory. Distant collisions as well as a more vigorous expression for close collisions are taken into account, revealing a significant difference for ion-ion relaxation. By using Bethe's formula for the stopping power of an energetic particle injected into a solid and redefining the ionization potential into a "plasma potential" by dimensional arguments, an expression for the plasma case is derived and shown to be in qualitative accord with the rigorous expression for relaxation.
