MACKLIB-IV is a library of nuclear response functions (activities) for 49 materials of interest in fusion and fusion-fission hybrid systems. It employs the CTR energy group structure of 171 neutron groups and 36 gamma groups. Included in the library are neutron and gamma KERMA factors, gas production and tritium breeding functions, and all important reaction cross sections. The following materials are included: H, He, 6Li, 7Li, Be, 10B, 11B, C, N, O, F, Na, Mg, Al, Si, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Nb, Mo, Ta, 182W, 183W, 184W, 186W, Pb, 232Th, Pa, 233U, 234U, 235U, 236U, 238U, Np, 238Pu, 239Pu, 240Pu, 241Pu, 242Pu, 241Am and 243Am.
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.
