Abstract
The ion wake-field effects on the elastic electron-dust collisions are investigated in complex dusty plasmas. The eikonal method is employed to investigate the behaviors of the scattering phase shift and scattering cross section due to the variation of the strength of the wake-field. It is shown that the eikonal phase shift decreases with an increase of the Mach number and increases with an increase of the impact parameter. It is also shown that the eikonal phase shift decreases with increasing Debye length. The eikonal cross section for the elastic electron-dust collision is found to be increased due to the influence of the wake-field. In addition, it is found that the wake-field effect on the eikonal cross section is almost independent of the Debye length.
