ZZ LAHIMACK, Multigroup Neutron and Gamma Cross-Section and Response Function up to 800 MeV

Description of program or function: - Format: ANISN (using COPYBL to convert from EBCDIC to binary) - Number of groups: 9 neutron groups from 800 MeV to 50 MeV; 21 gamma-ray groups from 14 to 0.01 MeV. - Nuclides: H1, C, O, Al, Si, Fe, Pb; W (x-sections only); N, Ca (response functions only). - Origin: LANL transport cross sections; ORNL library HILO; response functions created by HETC (above 20 MeV), and collapsed from MACKLIB-IV (below 20 MeV). The energy range of the library, from thermal to 800 MeV is relevant to the solution of shielding, nuclear heating, and other radiation protection problems connected with the accelerator neutron sources e.g. spallation target. The data contains 10 elements of shielding and biological importance. They can easily be implemented to the neutron transport codes like ANISN and DOT by using the activity option
