Electronic Nuclear Data Access

Introduction

The National Nuclear Data Center (NNDC) and other members of the IAEA-sponsored International Nuclear Structure and Decay Data (NSDD) and Nuclear Reaction Data (NRDC) Networks and the U.S. Nuclear Data Program (USNDP) provide electronic access to many of the bibliographic and numeric databases maintained by members of these groups. Access is available by anonymous FTP and the World Wide Web. Some databases or programs also are available on CD-ROM from individual Centers.

The contents of these various services are changing and growing continually, as are the methods of accessing them. Most of the WWW home pages listed below contain current links. If you have problems or questions, please contact the NNDC at services@bnl.gov.

The NNDC, the International Atomic Energy Agency Nuclear Data Section (NDS), the OECD Nuclear Energy Agency Data Bank (NEADB) and the Russian Nuclear Data Center (RNDC) maintain databases and provide services covering a wide range of nuclear science. The databases and services available from these centers are listed first followed by the methods of electronic access to these centers. Next, other members of the NSDD, NRDC, and USNDP providing electronic access to nuclear data are listed in alphabetical order.

Other data centers and Web sites of interest may be accessed through the NNDC WWW site or the other Web sites listed below. The USNDP home page (http://www.nndc.bnl.gov/usndp/) contains this information organized by subject or discipline and from the viewpoints of various user communities.

Members of the USNDP receive some or all of their funding from the Division of Nuclear Physics, Office of High Energy and Nuclear Physics, US Department of Energy. http://www.pixe.lth.se/glossary/index.asp?gloss=ndgloss contains a useful glossary of Internet and nuclear data terminology.

Databases and Services at the NNDC, NDS, NEADB, and RNDC

The NNDC, NDS, NEADB, and RNDC mirror the information available at these four core centers although there are some differences in the contents and version dates of the databases.

Division of Nuclear Physics, Office of High Energy and Nuclear Physics, US Department of Energy

The Division of Nuclear Physics supports a broad program of basic research in nuclear physics. The Division's World Wide Web site (http://www.sc.doe.gov/production/henp/np/index.html provides an overview of its research program, programmatic activities, and links to research facilities at universities and national laboratories, to some major experiments, and to research publications. One of the Division's sub-programs, Low Energy Nuclear Physics, supports information services on critical nuclear data, and the compilation and dissemination of accurate and complete nuclear data information that is readily accessible and user oriented.
