Of the processes that reduce the intensity of X-rays passing through matter, photoelectric absorption, scattering and extinction are important for the X-ray wavelengths used in crystallography. This chapter discusses each in turn. Different kinds of absorption corrections are described and parameters for use in calculating absorption corrections are tabulated.


  • absorption;
  • absorption corrections;
  • attenuation coefficients;
  • dispersion;
  • extinction;
  • mass absorption coefficients;
  • photoelectric absorption;
  • transmission coefficients;
  • X-ray absorption
