description

This WWW form provides a front-end to a calculation of the anomalous dispersion corrections to the X-ray atomic scattering factor by the method outlined in the reference. The WWW form returns the raw output from the FORTRAN program.

Ref: D.T. Cromer and D. Liberman; J CHEM PHYS 53.5 (1970) 1891 - 1898.

The program was originally written, as far as I know, by Dr. A. Habenschuss of the Oak Ridge National Laboratory. The VAX FORTRAN source code came from Dr. Jerome B. Cohen, Department of Materials Science and Engineering, Northwestern University, Evanston, Illinois. I modified the "front end" to make it somewhat user-friendly and computer/compiler independent.

comments

We know that the graphics are very crude. But very portable. So (2003-Dec), we have included a JPEG plot in addition to the raw text output from the FORTRAN program.

The calculations are not available for Hydrogen (H,1), Helium (He,2), Einsteinium (Es,99), Francium (Fm,100), Mendelevium (Md,101), Nobelium (No,102), Lawrencium (Lw,103), or higher atomic numbers.
