Abstract : The effect of a small amount of twobody scattering on the twostream instability that occurs in a plasma of contrastreaming electrons and ions is investigated mathematically. This is done by assuming the electronion collision frequency is small and making a perturbation expansion in this quantity. The FokkerPlanck scattering formula for the coulomb interaction is used. As the ordered streaming energy of the electrons is thermalized, enhanced Landau damping competes with the growth of the instability. (Author)
