| Abstract: | The salient features of soliton
dynamics generated with the interaction of negative ions in inhomogeneous
plasma has been studied through the derivation of modified Korteweg-de Vries
(mK-dV) equation. Because of the complexity of plasma non-linear wave equation,
the usual steady state method found to face difficulty to yield the soliton
solution. The new approach known to be sine-cosine method shows the success on
yielding soliton propagation along with a precursor of growing mode. The study
has been furthered with higher order non-linear effect resulted on the inherent
behaviour of precursor and relates the observations with actual experimental
observations. The study also shows that the soliton along with the precursor,
due to the interaction of negative ions, might collapse expecting a source of
high-energy with radiation-like called soliton radiation. These observations
could be an advanced knowledge on soliton dynamics in Townsend discharge plasma
and thus might be of interest to yield soliton propagation along with precursor
in laboratory and space plasmas. |
