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

Abstract

In an unbounded, collisionless and unmagnetized plasma consisting of positive and negative ions together with non-thermal electrons, first and second order amplitudes and widths of the ion-acoustic solitary waves are discussed here properly along with the effect of the concentration of negative ion and temperature of both positive and negative ions.

Analytical study of ion-acoustic soliton in single temperature nonisothermal electron

“…In a collision less, unmagnetized with non-relativistic or relativistic plasma, solitary waves in isothermal plasmas have been investigated theoretically and experimentally by many Physicists [1][2][3][4][5][6][7][8][9][10][11][12] . In case of non-Maxwellian electron distribution, the present author [13][14] also discussed compressive solitary waves in a plasma having warm positive ion and warm negative ion. Many scientists in plasma took different types of electron distribution function for studying various kinds of solitary waves pointing out some restrictions on electrostatic potential and phase velocity.…”
