Abstract
Based on the x-ray intensity field due to a spherical wave obtained in Part I, the integrated power ratio of the Bragg-reflected wave is presented for wedge-shaped crystals. No approximation is used except the so-called two-beam approximation. In parallel-sided crystals, the result is practically the same as the previous result obtained by assuming smallness of absorption, based on the plane-wave theory. The result can be used for understanding the traverse-type x-ray topograph.
