  • Abstract
    A detailed quantitative analysis of the various Bragg and Laue components of the integrated reflection power ratio for cylindrical crystals, and the dependence of these components on the Bragg angle, (theta)B, the reduced radius, (tau)0 = (sigma)0(rho), and the ratio of absorption coefficient to diffraction cross section, (mu)/(sigma)0 = (xi)0, is presented. The result indicates that the percentage of Laue and Bragg components of the integrated reflection power ratio is larger than 50% when (theta)B <=20(degree) and (mu)(rho)<=1, and when (theta)B=>10(degree) and (mu)(rho)=>5. The reflection power ratio profile for cylindrical crystals with large (mu)(rho)is also discussed.
