Energy loss and mean free path of electrons in a hot thermal plasma
Abstract
The energy loss of test electrons and the effective cross section for electronelectron scattering in hot thermal plasmas are given for arbitrary temperatures and electron energies. In the nonrelativistic limit the resulting integrals are performed analytically so that the mean rate of energy loss and the mean free path of electrons can be expressed by simple functions. Comparison of the results with the approximation of target electrons at rest shows that the thermal motion of the plasma electrons has to be taken into account whenever the kinetic energy of the test electrons does not considerably exceed the mean thermal energy of the plasma particles.
