The existence of both KdV and mKdV solitons has been established for alpha (= ion to electron temperature ratio) > beta (= negative ion to electron temperature ratio) and alpha < beta, which is the new outcome of the current investi-gation. Furthermore, the existence of both compres-sive and rarefactive solitons for Q' > 1 and Q'< 1 has been demonstrated.
