Two-body relaxation in relativistic thermal plasmas.

Monthly Notices of the Royal Astronomical Society, 202:467-481, 1983.


An exact expression for the average energy exchange in a relativistic two-body collision between isotropic particle distributions is calculated. This is used to find the relaxation time-scale for particles with a Maxwellian distribution function. These time-scales are compared with important energy loss time-scales at temperatures \(kT/m_e c^2 \gtrsim 1\).
