Atomic Data for Astrophysics - Photoionization; Recombination; Collisional ionization and autoionization; Charge transfer; Auger processes Energy levels, wavelengths, transition probabilities; Collision strengths, excitation rates; Stark broadening; Opacities; Fortran subroutines and other Databases for Atomic and Plasma Physics.
Databases for Atomic and Plasma Physics - Collection of several links to databases for Atomic and Plasma Physics: Opacities, Atomic spectra, Electron-Impact Ionization Cross Sections, Electron binding energies, X-Ray emission lines, Photoionization, Recombination, Collisional Ionization and Autoionization, Charge Transfer, Auger Processes, Energy Levels, Wavelengths, Transition Probabilities, Collision Strengths, Excitation Rates, Stark Broadening, and much more (from: WIS Plasma Laboratory).
FUSE Atomic Data Page - Provides atomic data (statistical weights, transition probablilities, and oscillator strengths) for elements Hydrogen (including Deuterium) up to Ge (atomic number 32), plus Tables of UV lines sorted by wavelength.
IAEA Nuclear Data Services - Provides direct WWW access to databases, documents, programs and files. Maintained by the IAEA's Nuclear Data Centre.
National Nuclear Data Center - The National Nuclear Data Center (NNDC) is funded by the U.S. Department of Energy to provide information services in the fields of low and medium energy nuclear physics to users in the United States and Canada. In particular, the Center can provide information on neutron, charged-particle, and photonuclear reactions, nuclear structure, and decay data.
X-Ray Absorption Coefficients - Program to calculate X-ray absorption coefficients, also edge energies, fluorescence yield; MUCAL on the Web Mucal on the web.
X-Ray Emission Lines - K-level and L-level emission lines in KeV. Values are from J. A. Bearden, "X-Ray Wavelengths", Review of Modern Physics, (January 1967) pp. 86-99.
X-Ray Interactions with Matter - Atomic x-ray scattering factor files, x-ray properties of the elements, a calculator for synchrotron bent magnet radiation and more; published by the Center for X-Ray Optics at LBNL.
X-Ray WWW Server - This is the repository of the COREX bibliography and database, the Henke atomic scattering factors, and other information of interest to x-ray spectroscopists. It provides links to additional locations for information about x-ray research.
