Influence of Non -thermal Electron Parameter on Heavier Masses of Negative Ion Plasma

Abstract

In presence of non-thermal electrons, theoretical investigations on ion-acoustic solitary waves are made in a collisionless unmagnetized warm plasma consisting of positive and negative ions by the well known pseudopotential technique. The influence of non-thermal electron parameter() on heavier masses (Q) of negative ion plasma for Sagdeev potential function[ ()], first (1)and second (2)order solitary wave solutions are mainly analysed and discussed here properly.
