3. DESCRIPTION OF PROGRAM OR FUNCTION

DECNET is a library for fusion damage computations of 175 neutron + 42 photon VITAMIN-J energy group with the standard weighting function: Maxwellian (at the temperature to which the material is referenced) + 1/E + Fission Spectrum + 1/E + Fusion Peak + 1/E; it includes neutron kerma and gamma-ray production data from radioactive nuclei at 3 temperatures with the same materials of ZZ-GEFF-2-GENDF (see below) from 1-H-1 to Bi-209, mostly taken from EFF-2 with some nuclides from JEF-2.2 - Ag-107, Ag-109, Cd, the 6 Hf isotopes and the 4 W isotopes; however the list of the materials disagrees with that of GEFF-2 in that all elemental nuclides have been split into the components isotopes to follow the respective decay chain and not all materials of GEFF-2 produces nuclei which disintegrate.
The library has been produced by the DECKER code which has been developed for this purpose. The format of the library is GENDF.

4. METHOD OF SOLUTION

The library has been produced by the DECKER code developed at ENEA Bologna for this purpose. The code reads the nuclide(s) for which decay kerma and photon production are requested and looks for the necessary data on the RDD (Radioactive Decay Data) file from JEF-2.2

7. UNUSUAL FEATURES OF THE PROGRAM

The structure of the library, being fully GENDF, is slightly modified in the contents of the various fields.
The library includes only MF=3 and MF=16 with kerma and gamma-ray production matrices, respectively. MT values are assigned with the usual NJOY conventions for kerma, i.e. 300+MT. NOTE THAT THE ASSIGNED MT IS REFERRED TO THE REACTION FROM WHICH THE FATHER NUCLIDE PRODUCES THE CURRENT NUCLIDE: THIS IS IDENTIFIED BY THE COUPLE ZA, AWR AT THE BEGINNING OF THE SECTION IN THE POSITION C1, C2 OF THE HEAD RECORD. ALL SUBSEQUENT LIST RECORDS WILL HAVE IN POSITION C1 THE TEMPERATURE AND IN POSITION C2 THE DECAY TIME IN SECONDS. This should allow users to account the decay events within some selected time. Thus for the reaction: 1-H-2(N,G)1-H-3 the first two records of the (n,gamma) kerma are (note some fields are compressed):
1.00300+ 3 2.99015+ 0 1 1 0 175 128 3402 5 2.93600+ 2 3.89105+ 8 2 1 2 1 128 3402 6
