Abstract :
We have analyzed the formation of solitons in a beam plasma system consisting of warm relativistic negative ions. The subsequent destruction of the nonlinearity of Korteweg-deVries equation near the critical density of negative ions and evolution of the shock wave are discussed in detail. The physical attributes of the ion-acoustic solitary wave and shocks are depicted graphically for the plasmas having (H+, Cl-) ions, (H+, O-) ions, (H+, SF5-) ions, (He+, Cl-) ions. It is found that mass ratio of negative ions and positive ions, relativistic effect and negative ion concentration have important contribution on the formation of solitons and shocks in the plasma
