Atomic Spectra Bibliography Databases at NIST

NIST’s Atomic Spectroscopy Data Center maintains three online Bibliographic Databases (BD) containing references to papers with atomic data for controlled fusion research, modeling and diagnostics of astrophysical and terrestrial plasmas, and fundamental properties of electronic spectra of atoms and ions. The NIST Atomic Energy Levels and Spectra BD now includes about 11800 references, mostly for years 1967–2008. The NIST Atomic Transition Probability BD, v. 8.1 with its 7600 references mainly covers years 1964–2007. The NIST Spectral Line Broadening BD, v. 2.0 has 3840 references, mostly for 1978–2006. All three databases are maintained in a unified database management system that allows us to quickly update the contents. An automated Data Entry module makes it easy to enter and categorize the data. The system allows us to keep the contents of all BDs up to date. Updates become available to users on the next day. A number of enhancements made since last year, such as direct links to articles in online journal archives and inclusion of digital object identifiers, greatly increased public usability of the databases.
