Formation of interference fringes in the Bragg–(Bragg)m–Laue mode

Formation of interference fringes in the Bragg–(Bragg)m–Laue mode X‐ray interference fringes in the beams diffracted from a lateral surface of a thin plane‐parallel crystal are measured and analyzed using Wagner's approach [Wagner (1956), Z. Phys.146, 127–168]. It is found that the fringes are caused by the interference between the internal waves excited by the incident beam in both the Bragg–Laue case and the Bragg–Bragg–Laue case. The period of the interference fringes is shown to be proportional to the distance between the incident point of the X‐ray and the crystal edge, and to be inversely proportional to the crystal thickness. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Crystallographica Section A Foundations of Crystallography Wiley

Abstract

X‐ray interference fringes in the beams diffracted from a lateral surface of a thin plane‐parallel crystal are measured and analyzed using Wagner's approach [Wagner (1956), Z. Phys.146, 127–168]. It is found that the fringes are caused by the interference between the internal waves excited by the incident beam in both the Bragg–Laue case and the Bragg–Bragg–Laue case. The period of the interference fringes is shown to be proportional to the distance between the incident point of the X‐ray and the crystal edge, and to be inversely proportional to the crystal thickness.
