The computer code MACK was used to produce averaged neutron reaction cross sections and KERMA factors in the 100-group GAM structure. Data are included for materials commonly used in CTR neutronics studies. The library is distributed in card image FIDO format; the array structure can be read directly into the transport code ANISN in order to calculate reaction rates. A simple retrieval program is included which can be used to edit the library, mix cross sections or collapse the group structure. The output is either in FIDO format, or in binary ANISN library tape format.
