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