ION-ACOUSTIC SOLITONS IN A PLASMA WITH RELATIVISTIC ELECTRONS IN THE PRESENCE OF NEGATIVE IONS
In the presence of negative ions, relativistic electrons have been investigated in a plasma through Korteweg-de Vries (KdV) equation considering relativistic effects. Both fast compressive and rarefactive solitons are found to exist for (= negative to ion mass ratio) in the plasma model. But only fast compressive solitons exist for The higher density ratio gives higher amplitudes and widths for
negative ions, soliton, relativistic electron, KdV.
