Abstract : Using integral form of governing equations in terms of pseudo potential ion-acoustic double-layers have been investigated theoretically in a multicomponent plasma consisting of two types of cold positive ions and two- temperature isothermal electrons. The mathematical technique used here has advantage over other conventional methods to study higher order nonlinear and dispersive effects on double layer formation. Conditions are obtained for the existence of ion-acoustic double-layers in the studied plasma. The effects of temperature and density ratios of the two types of electrons and the ratio of masses of the two types of positive ions on the double-layer formation and structure are also investigated. They are shown to have significant effects on the excitation and structure of the double-layers. The importance of this investigation has also been pointed out.
