Kurzfassung:
It is proved analytically in the three-fluid theory of a plasma that the effect of negative ions on the oscillating-two-stream instability results in a change of the frequency mismatch between the electromagnetic pump and the electron plasma wave. Ion thermal and collision terms are assumed to be negligible. This negative ion effect can completely detune and suppress the instability, if the number density ratio of negative to positive ions is greater than 2(v20/v2th), where v0 is the oscillation velocity amplitude of electrons under the pump and vth is the electron thermal speed.
