This interactive periodic table created by the Center for Synchrotron Radiation Research and Instrumentation provides x-ray properties for the elements. For each element, users can find data on its chemical properties, edge energies, edge jumps, and fluorescence yield. By adding an energy value, users can receive x-ray cross-sections at that energy, which includes photoelectric, coherent, and incoherent data. The website also provides a link providing the computer technology used to calculate the x-ray cross sections. Those involved with radiation research will find this reference useful.
