摘要：

A theoretical and experimental study has been done on the relationship between Darwin and Ewald curves. The Ewald formula is described in the frame of successive reflections at the front and rear surfaces, and a relation of R(E)=2R(D)/(1 + R(D)) has been obtained between the Ewald formula R(E) and the Darwin formula R(D) in the case of non-absorbing crystals. Both the Darwin and Ewald curves have been observed by controlling the successive reflections by using a tailless incident beam obtained through a channel-cut monochromator in the double-crystal parallel setting of Si crystals.
