Extract

Several literature references address the relationship between the reciprocal of the absorption coefficient and the Compton scatter peak, intensity. Most workers use a Compton scattered tube line in the calculation of background; however, use of Bremsstrahlung scatter in the present work is also valid for this calculation. Background calculation for a fixed-angle monochromator is desirable since the background cannot be measured off peak. A method for calculating background for fixed-channel instruments by summing the calculated Rayleigh and Compton scatter intensities is presented in this paper.
