By using the Sagdeev pseudopotential method, ion-acoustic solitary waves are
studied in a collisionless, unmagnetised single electron-temperature plasma with
adiabatic positive and negative ion drifts having equal ion-temperatures
(particular case). The effect of ionic temperature and negative ions on solitary
waves is discussed for the plasmas having (He+, O-),
(He+, Cl-) and (H+,
O-) ions.
