NEA On-line Services are open to registered scientific users in the seventeen member states of the NEA Data Bank. New users register via the on-line form at Web address www. nea. fr The site offers access to a wide range of databases (ENSDF, NSR, NUDAT, as well as experimental data (EXFOR), bibliographic reference to neutron induced reactions (CINDA), evaluated data files (including JEF, ENDF/B and JENDL) and the NEA Thermochemical Data Base (TDB)). All data libraries have on-line search and download facilities.

On-line services can be accessed through the Web at the following address: http://www. nea. fr/
