给出了各向同性对等离子体中两体过程的反应速率。这些速率在中等相对论能量上是准确的，并且是作为入射粒子能量的函数给出的，而不是在热分布上积分。所考虑的过程是：康普顿散射、对湮灭、双光子对产生、库仑散射和e-e韧致辐射。对于前三个过程，计算了末态的平均能量及其在能量中关于其平均能量的色散。文中给出了已证明有用的近似表达式。这些结果已列成表格，用于对等离子体的动力学方程研究。
Reaction rates are given for two-body processes in an isotropic-pair plasma. The rates are accurate over mildly relativistic energies and are given as functions of the incident particle energies rather than integrated over a thermal distribution. The processes considered are: Compton scattering, pair annihilation, two-photon pair production, Coulomb scattering, and e-e bremsstrahlung. For the first three processes, the mean energy of the final states together with the dispersion in energy about their mean energies are computed. Approximate expressions are presented where these have proven useful. The results have been tabulated for use in kinetic equation studies of pair plasmas.
