Abstract : Using integral form of governing equations in terms of pseudopotential the effects of higher order nonlinearity and dispersion on the propagation of ion-acoustic solitary waves have been studied in a multicomponent plasma consisting of two types of cold positive ions and two- temperature isothermal electrons. Expressions for soliton width and Mach number as a function of soliton amplitude have been obtained including third order effects. Higher order solitons are shown to move faster than the lowest order soliton but with smaller amplitude and width.

Reviewer Comments : The subject deals with the propagation of solitary acoustic ion waves in multicomponent plasma. The effects of non-linearity and higher order dispersion are spotlighted. The adopted tool was the use of an integral form of governing equations in terms of pseudopotential. The study was mainly conducted on the basis of two descriptors: the Mach number and the soliton width as a function of the amplitude of its displacement. The topic is a kind of mathematical study of the non-linearity of a wave phenomenon. The technique used has an advantage over other conventional methods and can be adopted to study the higher order nonlinear and dispersive effects on solitary waves in other plasma environments.
