- Abstract
- Plasma screening effects on electron-dust grain elastic collisions in
dusty plasmas are investigated using the eikonal method. Attractive
interaction between the projectile electron and its own image charge
inside the dust grain is included to obtain the total interaction
potential between the projectile electron and the dust grain. The
semiclassical straight-line trajectory method is applied to the path of
the projectile electron in order to investigate the variation of the
eikonal phase as a function of the impact parameter, dust charge, and
Debye length. The eikonal elastic cross section substantially decreases
with a decrease of the Debye length. It is also found that the position of
the maximum cross section is shifted to a higher energy region with
increasing the dust charge.
