The accuracy of the Chebyshev expansion coefficients used for the calculation of attenuation correction factors for cylindrical samples has been improved. An increased order of expansion allows the method to be useful over a greater range of attenuation. It is shown that many of tehse coefficients are exactly zero, others are rational numbers, and others are rational factors of II-1. The assumptions of Sears (J.of Appl. Cryst. (1984), 17, 226-230] in his asymptotic expression of the attenuation correction factor are also examined Subject Added Entry - Topical Term Chebyshev expansion coefficients   Attenuation correction factors           Physical Location           Digital Copy Not Available          Add to Book Cart  |   Download MARC
