The effect of external magnetic field on the coherent to Compton scattering differential cross section ratios of elements in the range 20 ≤ Z ≤ 32

The coherent to Compton differential cross section ratios were calculated for elements in the range 20 ≤ Z ≤ 32 under an external magnetic field. The elements were irradiated by 59.54 keV gamma rays from an 241Am radioactive source. A Si(Li) detector was used to detect the scattered photons. It was observed that the coherent to Compton differential cross section ratios of the samples increase with the magnetic field (B = 0, 0.4, and 0.8 T). The theoretical results were obtained with two different methods and compared with the experimental results at 0 T.
