Molecular scattering differential cross sections of 59.5 keV γ-rays have been measured for some compounds of Na, Mg, Al, Ca, and Fe elements at 90°. The γ-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.

AbstractThe new x-ray analysis method using photoeleetron spectrometry demands knowledge of differential photoionization cross sections of the subshells of the converter atoms used as intermediary between the x-ray spectrum and the photoelectron spectrum. These differential cross sections were determined for the most appropriate converter, the neon atom, in the energy range from 50 to 3000 eV. The total photoionization cross section was partitioned into contributions that arise from single ionization in the various subshells and from multiple processes. We present in tabular and graphical form: a) 1s, 2s and 2p total subshell cross sections; b) 1s, 2s and 2p differential cross sections at 54.73°; and c) ls, 2s and 2p differential cross sections at 90°. Accuracy is considered to be better than 3%, 7% and 5% at all energies for 1s, 2s and 2p cross sections, respectively.
