3. DESCRIPTION OF PROGRAM OR FUNCTION

The Intermediate Energy Activation File IEAF-2001 is a compilation of neutron-induced activation cross sections in ENDF-6 data format for activation analyses in fusion technology and intermediate energy applications. The IEAF-2001 data library contains neutron-induced activation cross sections in the energy range 10-5 eV to 150 MeV for 679 target nuclides from Z=1 (hydrogen) to 84 (polonium). The total number of reaction channels with activation cross-section data is 134,431.  The European Activation File EAF-99 served as basis for the activation data below 20 MeV neutron energy. Threshold reaction cross-sections were evaluated on the basis of geometry dependent hybrid exciton and evaporation models using a modified version of the ALICE code. The IEAF-2001 data library can be processed with standard ENDF processing tools such as NJOY. A groupwise IEAF-2001 data library has been prepared for 256 energy groups in GENDF data format. The IEAF-2001 CD-ROM contains both the pointwise ENDF and the groupwise GENDF data files.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

An activation code capable of handling an arbitrary number of reaction channels is required for using IEAF-2001 data in activation calculations.

7. UNUSUAL FEATURES

IEAF-2001 activation data are stored as lumped MT=5 (n, anything)  cross-sections in the MF=3 section of the ENDF data file. Reaction product yields are stored in the MF=6 section using the LAW=0 representation.

8. RELATED OR AUXILIARY PROGRAMS

For processing the IEAF-2001 library the NJOY-code or another processing code is required.
