X0h

Web interface to compute crystal susceptibilities for medium-energy X-rays (0.1–10Å) for some crystals. Also provides the Bragg peak halfwidth, extinction and absorption lengths. Uses International Tables for f' and f" and interpolates them for intermediate wavelengths with the help of algorithm. Results must be treated with care in a close vicinity of absorption edges.
