Cross Section Area

In the present study, we have investigated scattering of an electron by hydrogen atoms in the presence of the elliptical polarized laser field. We have discussed the polarization effect of laser field on hydrogen atom and effect of the resulted polarized potential on differential scattering cross-section is studied. We assume the scattered electrons having kinetic energy (~3000 eV) and laser field of moderate field strength because it is permitted to treat the scattering process in first Born approximation and the scattering electron was described by Volkov wave function. We found that the differential scattering cross-section area increases with the increase of the kinetic energy of the incident electron and there is no effect of changing the value of polarizing angle on the differential cross-section with kinetic energy. We observed that differential scattering cross-section in elliptical polarization in the high energy region depends upon the laser intensity and the incident energy for a linearly polarized field.

Variation Tendency

Using the discrete dipole approximation method, the absorption, scattering, extinction efficiency factor and differential scattering cross section of four kinds of nano-graphite particles under different incident angle are numerical calculated, the result shown that the value of the absorption, scattering, extinction efficiency factor and differential scattering cross section of linear nano-graphite particles are symmetric on the incident angle. There are the same variation tendency of absorption and extinction efficiency factor changed with the incident angle, when the incident light parallel with the linear nano-graphite particles, both the absorption and extinction are the strongest, and when the incident light perpendicular the linear nano-graphite particles, both the absorption and extinction are the weakest. The variation tendency of scattering efficiency factor changed with incident angle depended on the number of single graphite and the arrangement of linear nano-graphite particles. The value of differential scattering cross section is the smallest while the incident light parallel with the linear nano-graphite particles, however, the biggest while the incident light perpendicular the linear nano-graphite particles.
