EFFECTS OF POSITRONS AND NONTHERMAL ELECTRONS ON THE ION-ACOUSTIC DOUBLE LAYERS IN WARM MULTICOMPONENT PLASMA
Journal of Applied Physical Science International,
Page 44-60
Abstract
The effects of isothermal positrons and nonthermal electrons on the ion-acoustic double layers in warm multicomponent plasma having positive and negative ions are studied using pseudo potential technique.. The expression of Sagdeev potential has been derived and the solution for ion-acoustic double layers has been obtained from the nonlinear equation. The profiles of double layers have been drawn taking different values of plasma parameters. It is observed that both compressive and rarefactive double layers would be excited in presence of positrons and nonthermal electrons in the plasma. The variation of amplitudes and widths of double layers have been discussed graphically for different positron density, positron temperature, nonthermal electrons, negative ion density including drift velocity of ions.
