Abstract:

This paper uses the transform and perturbation theory approach for the problem of longitudinal plasma oscillations. The plasma dispersion relation is shown to be a natural consequence of both the initial value problem and the problem of forced oscillations. Distribution functions of the form F sub Ov A sub n 1V-U to the 2n power sigma to the 2n power where n integer are investigated for both the single and double hump case. For the forced oscillations problem wave growth is obtained in space when the driving frequency is less than the plasma frequency. Wave growth is also described for the double hump distribution.
