X-Ray Attenuation Length
Explanation of Tables
- Attenuation Length
- The depth into the material measured along the surface normal where the
intensity of x-rays falls to 1/e of its value at the surface.
- The chemical formula is required here. Note that this is case sensitive
(e.g. CO for Carbon Monoxide vs Co for Cobalt).
- If a negative value is entered, the chemical formula
is checked against a list of some
If no match is found
then the density of the first element in the formula is used.
- Grazing Angle
- In keeping with the standard notation for the x-ray region the incidence
angle is measured relative to the surface (NOT the surface normal).
- A GIF 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. An encapsulated
postscript file is also offered for printing out the results.
