The National Nuclear Data Center (NNDC) collects, evaluates, and disseminates nuclear physics data for basic nuclear research and for applied nuclear technologies. The NNDC is a worldwide resource for nuclear data. The information available to the users of NNDC services is the product of the combined efforts of the NNDC and cooperating data centers and other interested groups, both in the United States and worldwide. The NNDC specializes in the following areas: Nuclear structure and low-energy nuclear reactions, Nuclear databases and information technology, Nuclear data compilation and evaluation.

The Metal Table Book 9.0 is the electronic implementation of the well-known Metal Table Book with all tables, text pages and formulae. The formulas can also be automatically converted according to the variables that are needed in practice. Values can be entered in the usual units and the results converted into other units. Values from tables and diagrams can be transferred directly into the formulas.

The Lund/LBNL Nuclear Data Search provides on-line access to data from the Table of Isotopes handbook. Data may be accessed via radiation or nuclide searches. Radiation searches may be conducted on several levels, from the more general (energy and energy type -- alpha or gamma), to the more specific (parent information, such as half-life, mass number, or element). Search returns are listed alphabetically or by energy and intensity.

Extensive mathematical resource, provided as a free service to the world's mathematics and internet communities as part of a commitment to education and educational outreach by Wolfram Research, makers of Mathematica. MathWorld is part of the parent encyclopaedia Eric Weisstein`s World of Science. It is sponsored by Wolfram Research Inc, the publisher of the Mathematica software system, together with the National Science Foundation. The concept is that entries are created and accepted by suitably qualified users without any special formalities. The editor in charge is Eric Weisstein. Although freely accessible, it is a professionally designed comprehensive and user-friendly database, which, in the style of the Mathematica software system, provides information on all areas of mathematics, including fundamentals and history, by means of applets for 3D graphics, animations and interaction. Suitable as a didactic tool for mathematics teaching from secondary level 1, for science studi...

BASE (Bielefeld Academic Search Engine) is one of the world's most voluminous search sengines especially for academic web resources, e.g. journal articles, preprints, digital collections, images / videos or research data. Other than search engines like Google or Bing BASE searches the deep web as well. The sources which are included are intellectually selected and reviewed. BASE is operated by Bielefeld University Library.

This database gives ground levels and ionization energies for the neutral atoms. The ionization energies in the table are based on a recent survey of the literature. A reference to one or another data compilation is given for a number of elements; the cited compilation gives the reference(s) for the original ionization-energy data.

The NIST X-ray Photoelectron Spectroscopy (XPS) Database gives easy access to the energies of many photoelectron and Auger-electron spectral lines. Resulting from a critical evaluation of the published literature, the database contains over 29,000 line positions, chemical shifts, doublet splittings, and energy separations of photoelectron and Auger-electron lines. A highly interactive program allows the user to search by element, line type, line energy, and many other variables. Users can easily identify unknown measured lines by matching to previous measurements.
