MEASUREMENT OF THE K X-RAY ABSORPTION JUMP RATIO OF ERBIUM BY ATTENUATION OF A COMPTON PEAK

摘要

The X-ray absorption jump ratio of erbium was measured with a high resolution intrinsic germanium detector by attenuation, with an erbium foil, of a Compton peak produced by the scattering of the 60 keV americium 241 X-rays. Data analysis consists of a deconvolution to find the true Compton peak shape and an integration of a parameterized expression of the attenuation coefficient adjusted by least squares. Our result has an error of 1.5% and compared with calculated data shows a difference of less than 5%.
