The modifications of the kinematical and extinction-corrected intensity profiles caused by the divergence of the incident synchrotron-radiation beam and the diffraction by the monochromator system are considered. Expressions for the integral width as well as the full width at half-maximum are presented and discussed. The theoretical results are compared with observations.
Keywords: synchrotron radiation.
