AnomDispVal

Calculate f', f'' and mu for a element/wavelength Pair.

This option offers numerical values for f', f" and mu for a single element at a given wavelength. Enter an element name and a wavelength for which the anomalous dispersion parameters are to be calculated as a keyboard instruction. The result will be in the same text/instruction window.

This feature might be needed for refinements with non Cu, Mo or Ag radiation data sets (e.g. synchrotron data).

The parameters are calculated following the S.Brennan & P.L. Cowan code (Rev.Sci.Instr., 1992, 63, 650).

Example: ANOM Br 0.77
