The Isotopes Project compiles, evaluates, and disseminates nuclear structure and radioactive decay data for basic and applied research. The Project is responsible for evaluating nuclear structure data for 51 mass chains (~600 nuclides), most of them in the region of A=21-30 and 166-193, and provides a leadership role in the evaluation of neutron capture and radioactive decay data. These evaluations are incorporated into the Evaluated Nuclear Structure Data File (ENSDF) and published in Nuclear Data Sheets (Academic Press). The group also evaluates neutron capture gamma-ray data with the International Atomic Energy Agency (IAEA), Nuclear Data Section and collaborates in neutron cross section measurements with the Institute of Isotope and Surface Chemistry (Budapest).
The Isotopes Project has played a seminal role in modernizing the nuclear data information system and developing effective data dissemination techniques. The Isotopes Project/Lund collaboration has developed a Nuclear Science References Search and a computer version of a Table of Radioactive Isotopes for the WWW. The latter allows searches for decay gamma-ray and alpha-particle emissions.
The 8th edition of the Table of Isotopes, John Wiley & Sons, Inc., was published in 1996, in both hard copy and CD-ROM versions, and updates on CD-ROM only were published in 1998 and 1999 . Isotope Explorer Version 2.2 (PC Windows 95/98/NT), a WWW-based software for searching, extracting, and displaying information from ENSDF and NSR, was released in January 1999, and the Internet Isotope Explorer Version 3.0 (JAVA/HTML) is now available. Additional publications from the Isotopes Project are the Table of Radioactive Isotopes, John Wiley & Sons, Inc., published in 1986, and the Table of Superdeformed Nuclear Bands and Fission Isomers (in collaboration with McMaster University, Canada), in Nuclear Data Sheets 97,241 (2002), on the Table of Isotopes CD-ROMs, and on the Internet.
The Project established an Educational WWW site in 1998,
Exploring the Isotopes, with a periodic table
interface to data on all isotopes for each element, and a
Glossary of Nuclear Science Terms.
In 2000 the Nuclear Structure Systematics WWW site
was added.
