Abstract

The free electron Compton scattering cross-section are given by klein-Nishima, calculated using photon with an energy of 662 keV scattered incoherently through angles from 0-120°. The Compton scattering effect was calculated producing a linear relationship between the reciprocal of the scattered photon energy and 1/E0as a function of (1-cos θ), where θ is the scattering angle. It was found that the energy of scattered gamma ray decreases as the scattering angles increase. The differential scattering cross-section as a function of θ was calculated.

 

Key words: Free electron, cross-section, scattering, photon.
