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 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.

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.

Nucleonica is a web portal developed for the worldwide nuclear science community. This resource replaces the traditional paper-based Karlsruhe Nuclide Chart. It offers online interactive nuclide charts, as well as reference data and searchable databases for internationally evaluated nuclear data. Nucleonica includes also application modules (decay, dosimetry and shielding, fission yields, range and stopping power, reactor irradiation, transport and packaging, etc.) with professional quality graphics. In addition, a variety of social networking tools are provided for scientific collaboration. To get access please register with your email address.
