JEFF-3.0 evaluated data library

This release has been superseded.

The Joint Evaluated Fission and Fusion File (JEFF-3.0) is an evaluated library produced via an international collaboration of Data Bank member countries co-ordinated under the auspices of the NEA Data Bank. The JEFF-3.0 library comprises at present only a general purpose library including thermal scattering law data for 5 materials.
This general purpose library was released in April 2002. It is in ENDF-6 format and contains data for 340 materials from 1-H-1 to 99-Es-255.

The complete library can be obtained in a number of ways:

1. Firstly maintaining a single file per isotope:

   File contents	File size
   Single compressed unix tar file	~33 MB
   DOS zipped file	~29 MB

2. As a single ENDF tape containing all isotopic data:

   File contents	File size
   Single ASCII ENDF tape for neutron data	~110 MB
   as above but zipped file	~26 MB
   Single ASCII ENDF tape for thermal scattering data	~9 MB
   as above but zipped file	~3 MB

Pointwise data are also available through the JANIS database.

Alternatively individual isotopic files are shown in the table below which gives the list of the JEFF-3.0 General Purpose materials and provides links to the corresponding evaluated files.
