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

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 and second order solitary wave solutions are mainly analysed and discussed here properly.
