Secondary Extinction in Cylindrical and Spherical Crystals forX-Ray and Neutron Diffraction

  • Published Date: December 31, 2000
  • The distribution of the reflection power ratio for a neutron or x-ray diffracted from a cylindrical crystal immersed in an homogenous incident beam is obtained by the numerical solution of the transfer equations for the first time. The profile well reflects all the physical properties of the absorption and extinction behaviour in the crystals. A systematic investigation of the secondary extinction for cylindrical and spherical crystals was carried out based on these results.
