Atomic Processes in Dusty Plasmas

Abstract

Various atomic processes are investigated in dusty plasmas including strong collective interactions. The effects of ion temperature on the electron–dust collision process are investigated in complex dusty plasmas. It is found that the eikonal scattering phase and electron–dust grain collision cross section decrease with decreasing ion temperature in dusty plasmas. The ion wake effects on the Coulomb drag force are investigated in complex dusty plasmas. It is found that the ion wake effects enhance the Coulomb ion drag force. The effects of electron temperature and density on the ion–dust grain bremsstrahlung process are investigated in dusty plasmas. It is found that the ion–dust bremsstrahlung radiation cross section decreases with increasing electron density in dusty plasmas.
