Simultaneous Excitation and Interaction of Nonlinear Ion-Acoustic and Beam-Mode Waves in an Ion-Beam-Plasma System

Abstract

The simultaneous excitation of nonlinear ion-acoustic and slow beam-mode waves has been experimentally found to occur in an ion-beam-plasma system. Further, the collision between the two different nonlinear modes is observed to result in the formation of a new mode, probably corresponding to a nonlinear explosive mode theoretically predicted by Yajima, Kono, and Ueda.
