【 摘 要 】

A rotating NaI(TI) scintillator detector and a collimated Cs137source producing gamma rays with an energy of 662 keV scattered incoherently by aluminum (Al) and copper (Cu) scatterers through the angles from 0 to 120°are used to study Compton scattering. The Compton scattering effect is investigated and found that the energy of scattered gamma ray decreases as the scattering angles increases. The differential scattering cross-section as a function of scattering angles is also measured. The experimental results of differential scattering cross-sections for Al and Cu scatterers were compared as a function of scattering angle and found to coincide at the higher angle region, although scattering cross-section for Cu are larger than Al scatterer at the lower angles region.
