Measurement of coherent to Compton scattering differential cross-section ratios of cadmium at different momentum transfer factors

摘要

The coherent to Compton scattering ratio is a useful technique because it is independent of the density of the material and the material is defined only by the atomic number. Also, this ratio is used where changes in the atomic number are important and changes in the attenuation coefficient are too small to detect. In this study, coherent to Compton scattering ratios of cadmium have been calculated at different scattering angles (90 degrees, 95 degrees, 100 degrees, 105 degrees, 110 degrees, 115 degrees, 120 degrees, 125 degrees, and 130 degrees). A high purity germanium detector was used. The coherent to Compton scattering differential cross-section ratios were plotted as a function of the scattering angles and constituted a best fit curve. It was observed that the coherent to Compton differential cross-section ratios decrease with an increasing scattering angle. The experimental results agree well with the results of the non-relativistic and relativistic form factor method.
