1. NAME AND TITLE OF DATA LIBRARY
LENDL-V: Lawrence Livermore National Laboratory Evaluated Nuclear Data Library in
2. NAME AND TITLE OF DATA RETRIEVAL PROGRAM
IAEA Nuclear Data Section, Vienna, Austria.
Lawrence Livermore National Laboratory, Livermore, California.
4. HISTORICAL BACKGROUND AND INFORMATION
Earlier versions of the Livermore Evaluated Nuclear Data Library ENDL were translated into
ENDF-IV format and packaged as DLC-34/LENDL. This version, in ENDF-V format, was assigned
a new DLC number.
5. APPLICATION OF THE DATA
This library contains the Evaluated Nuclear Data Library (ENDL) of the Lawrence Livermore
National Laboratory as of 1984. The library has been converted to the ENDF-V format by Lawrence
Livermore National Laboratory and the IAEA Nuclear Data Section. The library contains evaluated
neutron cross sections and differential data and neutron induced photon production data for 94
materials and includes a total of 231,348 records. All evaluations are complete, covering all relevant
reactions for incident energies from 10-4 eV to 20 MeV. All cross sections are represented in tabulated
linearly interpolable form; resonance parameters are not used.
6. SOURCE AND SCOPE OF DATA
The ENDL format is more general than the ENDF-V format in terms of the forms in which nuclear data can be represented in the ENDL format. As such it is not possible to accurately translate the entire ENDL library to the ENDF-V format. Evaluations which appear in the ENDL library in the ENDL format and not in the ENDF-V format include 2H and 9Be which use a double differential representation of the secondary energy-angle distribution in the ENDL format, which is not allowed in the ENDF-V format.
The materials included in the library are:
H, 3H, 3He, 4He, 6Li, 7Li, 7Be, 10B, 11B, 12C, 14N, 16O, 19F, 23Na, Mg, 27Al, Si, 32S, Cl, Ar, K, Ca, Ti,
