%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
ZZ-LA100 Evaluated Nuclear Data Library for Transport Calculations Involving Incident Neutrons and Protons of Energy Up to 100 MeV. This data base was developed for use in Monte Carlo or discrete ordinate transport codes, for example, the general Monte Carlo code MCNP. Various modules of the NJOY processing code system have been enhanced to permit processing of the ENDF/B-VI formatted evaluations into both continuous-energy and multi-group format. The transport data files for all 18 projectile-plus-target systems have been processed through NJOY, and coupled multi-particle, multi-group transport libraries for MCNP now exist. In addition, pointwise MCNP libraries to 100 MeV for incident neutrons have been prepared for the nine targets. The production version of the MCNP code is being modified to handle the new pointwise libraries. The production version of MCNP already supports the use of coupled multi-group libraries.

4. METHODS

The library is based on nuclear theory/model calculations with parameterizations obtained by matching calculations with experimental data, mainly using the PSR-125/GNASH statistical/preequilibrium/fission theory code. The library includes neutron- and proton-induced reactions for H1, Be9, C12, O16, Al27, Si28, Fe, W, and U238 and specifies the production cross sections and energy-angle correlated spectra of emitted neutrons, protons, alpha-particles, photons, and other significant charged particles. See reference LA-11753-MS for details.
