Abstract
The dispersion relation of an ion-acoustic wave propagating through a collisionless, unmagnetised plasma, having warm isothermal electrons a nd cold positive and negative ions has been derived. It is seen that t he ion-acoustic wave will be unstable in the presence of streaming of ions. Instability of the wave is graphically analysed for the plasma h aving (H+,O-) ions, (H+,O-2(-)) ions, (H+,SF5-) ions, (He+,Cl-) ions a nd (Ar+,O-) ions with different negative ion concentration and relativ istic velocity.
