Description

The dispersion relation of an ion-acoustic wave propagating through a collisionless, unmagnetised plasma, having warm isothermal electrons and cold positive and negative ions has been derived. It is seen that the ion-acoustic wave will be unstable in the presence of streaming of ions. Instability of the wave is graphically analysed for the plasma having (H+ ,O-) ions, (H+ ,O2- ) ions, (H+ , SF5- ) ions, (He+ , Cl-) ions and (Ar+ ,O-) ions with different negative ion concentration and relativistic velocity. 16 refs., 5 figs
