Input Explanation

General
All data should be provided. For elements form Ti through As input data already provided for K α line. You need Javascript enabled to use this feature. You are free to change any of this data to what you want.
The Atomic Scattering Factor
The real part of atomic scattering factor is subdivided in two fractions - atomic number and correction. These data available on B.L. Henke, E.M. Gullikson, and J.C. Davis, X-ray interactions: photoabsorption, scattering, transmission, and reflection at E=50-30000 eV, Z=1-92, Atomic Data and Nuclear Data Tables 54 no.2, 181-342 (July 1993). They are available online at the Center for X-Ray Optics, Berkeley Lab website.
Angle
According to the standard notation for the x-ray analysis the incident and exit angles are measured relative to the surface (NOT the surface normal).
Primary X-Ray
Preselected primary X-ray wavelength corresponds to Mo K α line (17.44 KeV).
Output
A PNG plot may be generated for quick viewing of the results. If you need anything fancier, the results are provided as a text file for use with your favorite plotting package.
