Simulation of Compton Double Scatterings of Circularly Polarized γ-Rays by Magnetic Electrons

In a recent study on the magnetic-electron Compton profile measurement by the author, an important correction of the spin-dependent multiple scatterings of circularly polarized γ-rays in a specimen was made on the basis of a computer simulation of the double scattering. This paper describes the detailed procedure of its simulation. It is found that the spin-dependent double scattering intensity is about one third of the ordinary double scattering intensity, due to the mutual cancellation among the intensities of spin-dependent double scattered γ-rays themselves.
