The determination of molecular scattering differential cross sections for compounds of some essential elements at 3.38 angstrom(-1) photon momentum transfer

摘要

Molecular scattering differential cross sections of 59.5 keV gamma-rays have been measured for some compounds of Na, Mg, Al, Ca, and Fe elements at 90 degrees. The gamma-rays of Am-241 were counted using a Si(Li) detector of EDXRF (energy dispersive X-ray fluorescence) system. The experimental results have been compared with non-relativistic and relativistic theoretical values.
