30th EPS Conference on Contr. Fusion and Plasma Phys., St. Petersburg, 7-11 July 2003 ECA Vol. 27A, P-4.160pd GENIE and DANSE: two Atomic and Molecular Data Web Search Engines for Fusion and Plasma Physics D. Humbert1, Yu. Ralchenko2, R. E. H.Clark1, K. Katsonis3 (1) IAEA, Nuclear data Section, Atomic and Molecular Data Unit, A-1400 Vienna, Austria (2) NIST, Atomic Spectroscopy GroupGaithersburg, MD 20889, USA (3) LPGP, UMR 8578, Université de Paris-Sud, 91405 Orsay, France GENIE and DANSE are two Internet Search Engines for Atomic and Molecular Data. Both of these engines allow a multi-database search and retrieval of numerical or bibliographical data. GENIE (GENeral Internet search Engine) is dedicated to numerical data and is freely accessible though the two URLs (http://www-amdis.iaea.org and http://gap3.lpgp.u-psud.fr/GENIE). DANSE (Data Around the Net Search Engine), still undergoing testing searches bibliographical data. 1. GENIE GENIE is a web search engine dedicated to numerical atomic data. Searches can be performed for energy levels and transition probabilities as well for electronic ionisation or excitation cross-sections. Data are retrieved simultaneously from these different databases: Oscillator strengths, transition probabilities and energy levels NIST Atomic Spectra Database: http://physics.nist.gov/cgi-bin/AtData/main_asd Kurucz’s CD-ROM 23: http://cfa-www.harvard.edu/amdata/ampdata/kurucz23/sekur.html Atomic Line List v.2.04: http://www.pa.uky.edu/~peter/atomic TOPbase (Opacity Project): http://heasarc.gsfc.nasa.gov/topbase/home.html Kelly Atomic Line Database: http://cfa-www.harvard.edu/amdata/ampdata/kelly/kelly.html MCHF/MCDHF Collection: http://atoms.vuse.vanderbilt.edu MCHF/ MCDHF ALL v.2.04 TOPbase Kurucz *(1,( Kelly Curl – background browser 30th EPS Conference on Contr.

A user is allowed to select one or more databases for querying. The original format of the query output is retained for each of the databases. Finally, a short description is provided for each of the databases. Links to original databases Short description of original databases 2. DANSE DANSE is dedicated to atomic and molecular bibliographical data. It retrieves simultaneously data from the 3 well-known bibliographic databases: AMBDAS at the IAEA: http://ripcrs01.iaea.or.at/AMBDAS/ GAPHYOR at LPGP: http://gaphyor.u-psud.fr/gaphyor/gaphyor.html CFADC Database at.

Fields covered are: 1. Electronic collisions 2. Heavy particles collisions 3. Photonic collisions 4. Gas-surface interactions 5. Properties of atoms and molecules A user is allowed to select one or more databases for querying and the original format of the query output is retained for each of the databases. Parameters and scientific fields may differ from one database to another one. Then upon a request one database can be automatically unselected. For example for “Properties of Atoms and Molecules”, the CFADC Bibliographic Database is unselected as this database does not include this kind of data. The input parameters can be either: • Categories with their range of processes • One or two reactants with their ionization state • One surface • One isoelectronic sequence • KeywordsOne author • A range of years 30th EPS Conference on Contr. Fusion and Plasma Phys., St. Petersburg, 7-11 July 2003 ECA Vol. 27A, P-4.160pd 4 of 4 Before a beta version of the search engine becomes available, some lacks and inconsistencies in the table of processes have still to be addressed. Therefore the divulgation of DANSE on the web has been postponed to the end of this year.
