Analytical study on the existence of ion-acoustic solitary waves in a plasma consisting of warm streaming ions and nonthermal electrons

Influence of Non -thermal Electron Parameter on Heavier Masses of Negative Ion Plasma

“…In absence of cold negative ion ( 0 = 0, = 0) and for 0 → 1, inequality (20a) supports Ref. 16 . Again in another words for absence of non-thermal electron (β = 0), inequation (20a) supports Ref.…”

“…Again when njo = 0(i.e. negative ions are absent) we get that form of (ф) that Paul et al 16 obtained. This Sagdeev potential function (ф) in (15a) and (15c) is more general form than Ref.…”

“…Ion-acoustic solitary waves have been investigated theoretically by a large number of scientists [1][2][3][4] Again Paul et al 16 studied analytically the non-thermal plasma with positive ion only. The present author also investigated the same non-thermal plasma with positive and negative ion drifts highlighting the higher order solitary wave solutions, stability of these solutions and comparison of first and second order amplitudes and widths in presence 17 and in absence 18 of positron.…”

Effect of Concentration of Negative Ion and Temperature of both Ions on Amplitude and Width for Non-Thermal Plasma

“…Again Bhattacharaya et al [11] studied theoretically the effects of non-thermal electrons with cold positive and negative ions on ion-acoustic solitary waves in a bounded plasma and obtained both compressive and rarefactive solitons without considering the ion temperature. Paul et al [12] studied the non-thermal plasma with warm positive ions in a new analytical way and obtained some necessary and sufficient conditions for the formation of ion-acoustic solitary waves with some special observations. In spite of this, they also found the sagdeev potential function 𝛙 for the same plasma and obtained the condition for the existence of a potential well with special attention of the critical values of the plasma parameters for solitary wave solutions.…”
