- Abstract
- Nonlinear effects on the bremsstrahlung process due to ion-dust grain collisions
are investigated in dusty plasmas. The nonlinear screened interaction potential is
applied to obtain the Fourier coefficients of the force acting on the dust grain.
The classical trajectory analysis is applied to obtain the differential
bremsstrahlung radiation cross section as a function of the scaled impact
parameter, projectile energy, photon energy, and Debye length. The result shows
that the nonlinear effects suppress the bremsstrahlung radiation cross section due
to collisions of ions with positively charged dust grains. These nonlinear effects
decrease with increasing Debye length and temperature, and increase with increasing
radiation photon energy.
