On the characteristics of head on collision of dust ion acoustic solitons in the adiabatic dusty plasmas

Based on a one-dimensional mode, the characteristics of the head on collision between two dust ion acoustic solitons (diass), propagating in opposite directions in adiabatic dusty plasmas composed of adiabatic non-inertial electrons, adiabatic inertial ions and immersed (negatively/positively) charged dust grains have been investigated. the extended poincare–lighthill–kuo (plk) method has been used to obtain two side korteweg-de vries (kdv) equations for diass. the analytical phase shifts and trajectories after collision of two solitons are given. the effects of adiabaticity of electron and ion fluids, concentration of negatively/positively charged static dust particles and ion temperature to electron temperature ratio on the phase shift are studied. it is found that these factors significantly affect the phase shifts.
