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.
