| Abstract: | Propagation of ion acoustic waves in plasmas containing electrons, positrons and high relativistic ions is investigated. It
is shown that the Korteweg-de Vries (KdV) equation describes the nonlinear waves in this media. The amplitude and energy of
the KdV solitary waves are derived and the effects of relativistic ions on these quantities are discussed. |
