Title: Arbitrary amplitude solitons in a non-ideal dusty plasma with non-thermal ions

Abstract

The Sagdeev potential method is used to investigate the non-linear propagation of the dust-acoustic wave in a weakly non-ideal dusty plasma comprising a negatively charged dust fluid, Boltzmann electrons and non-thermal ions which are characterised by a non-thermal parameter {alpha}. The non-ideal effects of volume reduction and attractive cohesive forces are introduced by adopting the van der Waal's equation of state for the dust fluid. Both supersonic and subsonic solitons are found to exist for a non-ideal dusty plasma and comparisons are made with the ideal case. The upper limit of the range of values of the non-thermal parameter for which soliton solutions are admissible, is examined as a function of the non-ideal parameters.
