The Initial Behavior of Plasmons in the Presence of a Long Wavelength Large Amplitude Phonon.

Abstract

Using a one dimensional two-fluid model the behavior of electrostatic electron plasma oscillations in the presence of a large amplitude long wavelength ion acoustic wave has been studied. The electron waves are observed to collect initially in regions of maximum density gradients. The initial increase in the variance of the plasmon wavenumbers is quadratic in time. When the high frequency fields are characterized by a narrow spectrum in k-space, a solution of the fluid equations is obtained which exhibits these results. (Author)
