Study the Characteristic of the Coupling Parameter ( Г ) in Dusty Plasma by Computer modeling

Abstract

Computer modeling has been used to investing the Coulomb couplingparameter Г. The effects of the structure parameter K, grain charge Z,plasma density N, temperature dust grain Td, on the Coulomb couplingparameter had been studied. It was seen that the Γ was increasing withincreasing Z and N, and decrease with increasing K and T. Also thecritical value of Γ that the phase transfer of the plasma state from liquidto solid was studied.
