IAEA Nuclear Data Section - Vienna, Austria

Note: Unless indicated otherwise, the quoted data files, printed materials, or computer codes are available cost-free upon request. The major databases are available online within NDIS, the Nuclear Data Information System. FTP transfer can be arranged by e-mail exchange. When requesting data files or codes on magnetic tapes or diskettes, kindly give us your acceptable specifications:


 Magnetic tapes: specify acceptable density (1600 or 6250 bpi), maximum
 block size, and whether the data should be coded in EBCDIC, ASCII, or
 VAX-backup coding.  Only 9-track tapes are used.

 DAT tapes: 4 mm only, either in TAR format, IBM format or VMS format,
 uncompressed or compressed.  Preferable for very large data libraries
 (up to several Gigabytes).

 PC diskettes: DOS standard diskettes, either 3.5 inch or 5.25 inch. 
 Preferable for not too large files (if compressed up to several
 Megabytes).

 CD-ROM: Now available.  Recording format ISO 9660.  Please specify
 maximum file-name length on your system.

Staff changes in the Data Centre

After conducting a prolonged search, we are happy to announce the appointment, effective 21 November 1997, of Vladimir Pronyaev as the new Head of the IAEA Nuclear Data Centre Unit. Vladimir, who comes to us from the Obninsk Nuclear Data Center, is well known for his many contributions to the field of nuclear data measurement, calculation and evaluation. He is also a former staff member of Nuclear Data Section's nuclear data development unit (1980-84). We are also happy to report the return of Sofiate Aung from leave of absence, effective 1 December 1997. The departure of both Hans Lemmel and Sofie in late 1996 naturally placed a heavy burden on the remaining staff of the Data Centre. The NDS management wishes to take this opportunity to thank all of the centre staff for their hard work in providing continuity of services during this difficult period of transition. In particular, Otto Schwerer, our Online Services Manager, deserves special thanks for his outstanding efforts. We are also pleased to announce the arrival of Scott Miller of the University of Texas. Over the next 12 months, Scott will help us in improving our worldwide web interface and in formulating a strategy for dealing with the increased congestion on the Internet.

Worldwide Web

Implementation of direct web access to nuclear reaction databases on our "Nuclear Data Services" website is starting in December 1997 with EXFOR and CINDA. See http://www-nds.iaea.or.at with links to new retrieval forms.

New data libraries

CENDL-2.1R. 7 revised materials (Fe-nat, Fe-54,56,57,58, Hg-nat, Tl-nat) were received (1997) for the Chinese Evaluated Nuclear Data Library for neutron reaction data (CENDL-2.1). Available on computer media or online through NDIS. Summary documentation: IAEA-NDS-61, Rev. 4.

"Maslov" update 97/2. Evaluated neutron reaction data for Pu-238 and Pu-242 were added to this file containing evaluations for several Am and Cm isotopes. Summary documentation: IAEA-NDS-164 Rev. 2 (1997).

Included are A: actinide nuclear data (decay data, selected neutron cross-section data, fission-neutron data); B: fission-product nuclear data (decay data and selected neutron cross-section data); C: fission-product yield data. Summary documentation: IAEA-NDS-248, Rev. 1.

NUBASE. New database for experimentally known nuclear properties, by G. Audi, O. Bersillon, J. Blachot, A.H. Wapstra. Available from the Atomic Mass Data Center (AMDC), see below. Not available from IAEA. - NUBASE contains mass, isomeric excitation energy, half-life, spin, parity, decay modes and intensities for more than 3000 nuclides. Published in the journal Nuclear Physics, Vol. A624(1997), pp. 1-124. Available by anonymous FTP from csnftp.in2p3.fr, directory /pub/symfond/audi/mass, or consult the AMDC web site at http://csnwww.in2p3.fr/amdc/

Charts of nuclides

1996 Japanese Chart of Nuclides issued by JNDC and JAERI-NDC, compiled by T. Horiguchi et al. Desk chart showing decay modes and half-lives. Supplemented by 5 tables (periodic table of elements; fundamental constants; gamma-ray energy and intensity standards; alpha-particle energies and intensities; isotopic abundances and thermal neutron cross sections). A limited number of copies is available cost-free from IAEA. For a WWW version (containing additional data) see http://cracker.tokai.jaeri.go.jp/CN96/index.html.
