Abstract : The effect of a small amount of two-body scattering on the two-stream instability that occurs in a plasma of contrastreaming electrons and ions is investigated mathematically. This is done by assuming the electron-ion collision frequency is small and making a perturbation expansion in this quantity. The Fokker-Planck 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)
