ZZ-EFF1LIB is a fast neutron data library for the Los Alamos continuous energy Monte Carlo Code MCNP. The library contains cross  section data for 69 - light and structural material - isotopes mainly from the EFF-1 evaluation in the energy range 10**(-5) eV to 20 MeV. Isotopes of the following chemical elements are included: H, He, Li, Be, B, C, N, O, F, Na, Mg, Al, Si, P, S, Cl, Ar, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zr, Nb, Mo, Ag, Cd, In, Sn, Xe, Cs, Ba, Sm, Hf, Ta, W, Pb and Bi.

4. METHOD OF SOLUTION:  The ZZ-EFF1LIB was produced with NJOY-89.62 Module ACER.
