This periodic table interface was developed to easily acces the calculated atomic cross sections for photoionization and the related asymmetry parameters. The data are taken from: J.J. Yeh, Atomic Calculation of Photoionization Cross-Sections and Asymmetry Parameters, Gordon and Breach Science Publishers, Langhorne, PE (USA), 1993 and from J.J. Yeh and I.Lindau, Atomic Data and Nuclear Data Tables, 32, 1-155 (1985). The data shown here are those calculated in the dipole length approximation.

This is a beta version: comments are welcome.
