On the ion-acoustic soliton in a relativistic beam ion plasma system

The authors analyzed the formation of ion-acoustic solitons in a beam-plasma system, where both the beam and the ion were considered to be relativistic. The system is assumed to be nonisothermal. Both lower- and higher-order computations are performed, and the change of the wave profile is discussed, both in the lower and higher order. It is observed that both the amplitude and the width of the soliton change significantly in the presence of the relativistic effect and ion beam. The variations of these quantities with respect to v/sub 0//c, the ion-beam population, and the nonisothermality of the plasma are depicted graphically and compared with other results.<
