Determination of the X‐ray mass absorption coefficient by measurement of the intensity of Ag Kα compton scattered radiation

By utilizing a reflection geometry, an accurate mass absorption coefficient of a sample can be determined by measuring the Ag Kα Compton intensity. Intensities of Ag Kα Compton scattered radiation have been collected by using either the usual reflection geometry of a Philips PW 1450 automatic X‐ray spectrometer or a more refined reflection geometry, achieved on a Philips PW 1540/10A manual X‐ray spectrometer. The experimental results have shown that the relationship between the Ag Kα Compton intensity and the mass absorption is a logarithmic function. Our experimental results are not in agreement with those reported in literature, but a theoretical explanation to account for this fact has not been achieved as yet.
