Stability of weakly nonlinear ion sound waves with finite ion temperature
Abstract
The modulation instability of small-amplitude ion-acoustic waves is investigated in three dimensions for Ti<0 (ion temperature non-zero). Relevance of results to an experiment of Watanabe is discussed. Instabilities present in this experiment are seen to be due to three-dimensional rather than thermal effects and would also appear for Ti = 0.
