Ion Acoustic Solitary Waves in a Negative Ion Beam Plasma in Presence of Electron Inertia

R. Das, K. Karmakar

Abstract :

Ion acoustic solitary waves have been investigated in a three component plasma consisting positive ions, negative beam ions and electrons. Existence of both compressive and rarefactive solitons is studied through perturbative technique. The amplitude of compressive soliton decreases rapidly with an increase of i b m m Q = (= beam to ion mass ratio). Further, only rarefactive solitons are found to exist in 0.1≤ Q <1, 0.3≤ γ ≤ 0.8 and 0.1≤α ≤ 0.8 ( where U Vb γ = = beam to phase velocity ratio and 0 0 i b n n α = = beam to ion equiliium density ratio).
