Abstract

Progress continues on the development of databases for spectral properties of atoms and ions. Version 2.0 of the NIST Atomic Spectra Database (ASD) became available on the World Wide Web in March 1999. This version contains data for many maore spectra than version 1.3, which it replaced, and the web interface is much more flexible in terms of presentation options for the user. We are now working to further improve the user interface, expecially concerning ease of access to the references. The next version will provide hyperlinks from the spectrum page to references for the wavelengths and transition probabilities of the that spectrum. As a continuing effort we are working to expand the coverage of spectra. The NIST Bibliographic Database on Atomic Transition Probabilities has been updated recently, and the NIST Bibliographic Database on Atomic Spectral Line Broadening will be updated sometime during 2000. Some uses of the databases for wavelength calibration of vuv lasers, online modeling of plasmas, and searches for the transition probabilities for all downward branches to specific energy levels of a particular atom for plasma diagnostics will be described.
