X-ray spectra scattered at 90° by acrylic resin plates of various thicknesses are measured. The intensity and polarization Compton-scattered X-rays estimated from the spectra. As thickness slab increases, increases but decreases. optimal for a polarized fluorescence spectrometer is determined, which provides both high polarization.

Recent topics on magnetic Compton-profile studies are reviewed. A compact introduction describes that the X-ray magnetic Compton-scattering method can be used to measure the momentum density of magnetic electrons, which may be said to be the extreme space-time self correlation of spins. Some examples show that the magnetic Compton profile provides information about the spin component of a magne...
