| Abstract: | In this paper, the characteristics of ion acoustic solitary waves are studied in plasmas containing warm ion fluid, non-thermally
distributed electron and positron. We study the effects of non-thermal electrons and ion temperature on solitons by Pseudo-potential
method and show that the parametric region where ion acoustic solitons can exist is modified. We also obtain linear dispersion
relation by using the standard normal-modes analysis. |
