%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%


  FORMAT: ANISN



  NUMBER OF GROUPS: 46 neutron, 23 gamma-ray

  ORIGIN: ENDF/B-V (VITAMIN-E)



  WEIGHTING SPECTRUM: VITAMIN-E weighting functions



%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%


Based on ENDF/B-V data and a revaluation of Fe (MOD 3) which contains significant improvements, this library consists of 80 nuclides that can be used to solve typical calculations of interest to the DNA radiation transport community. Any computer code requiring multigroup cross sections can use the data.

Eighty materials from the DLC-113C/VITAMIN-E library which were available on October 30,1987 are included as a first part of the DABL69 library. These materials were collapsed using the AMPX code system with the VITAMIN-E weighting functions. The second part of the DABL69 library contains 8 additional materials including N-14, O-16, and steel using problem-dependent weighting functions generated by ANISN of a typical problem. DABL69 contains 46 neutron  and 23 gamma-ray energy groups. The Legendre order of expansion for  angular distribution is 5.

As in DLC-31, the neutron groups are tailored to allow for the major peaks and valleys in the total neutron cross sections of nitrogen, oxygen, silicon, and iron. On the other hand, the gamma-ray groups are tailored to allow accurate calculation of pair  production, annihilation photon transport, hydrogen capture and backscatter photon transport. In the neutron energy range 0.2 to 1.8 MeV, additional boundaries were added to the parent DLC-031 group structure to give better resolution in the region where the largest  fraction of the total KERMA frequently occurs.

Source spectra and response functions useful in radiation transport applications are included in the library. Elemental KERMA  factors are provided for nuclides ranging from H-1 to Am-243. Version A (D00130/I0360/00) includes card-image data files in both ANISN format and AMPX master format with KERMA factor data derived from DLC-060/MACKLIB-IV.

Version B (D00130/I0360/01) is available in ANISN card images in which the KERMA factor data has been replaced with data derived from DLC-160/KAOS-LIB/V.

8. RELATED AND AUXILIARY PROGRAMS

BCBN: Convert ANISN card-image data to binary format.
This data package was developed to supersede the DLC-31/FEWG1 cross section library which has been used for Defense Nuclear Agency radiation transport calculations. The availability of ENDF/B-V data  coupled with some evidence that the original group structure needed  some refinement, provided the driving force in the development of a
replacement for FEWG1 which is based on ENDF/B-V.
The energy group structure (46n,23g) is a subset of the VITAMIN-E group structure and is tailored to air-over-ground environments.
