Mucal on the web

Switch to the periodic table version of Mucal.

This is a program to calculate x-ray absorption coefficients. It uses the fortran subroutine mucal written by Pathikrit Bandyopadhyay. The sources for the subroutine (mucal_f and a c version, mucal_c) used to calculate the x-ray cross-sections are available.

If you want to know edge energies, fluorescence yield, etc. of an element fill in the symbol and submit query. For x-ray absorption coefficients, also fill in the energy of interest in the energy box.

Element Symbol:

Energy: keV   -   Please note that values above 500 will be treated as eV rather than keV

To submit the query, press: .

Program reference: P. Bandyopadhyay and C.U. Segre,

Calculations are based on data from: W.H. McMaster N.K. Del Grande, J.H. Mallett and J.H. Hubbell, "Compilation of x-ray cross sections", Lawrence Livermore National Laboratory Report UCRL-50174 (section I 1970, section II 1969, section III 1969 and section IV 1969).

Fluorescence yield data from: M. O. Krause, J. Phys. Chem. Ref. Data. 8, 307(1979).
