  WEIGHTING SPECTRUM:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
L26P3S34 is a library of group-averaged scattering cross sections and up to P3 matrices of elastic, inelastic and (n,2n) scattering for 26 groups materials for the computation of neutron transfer in shielding media. The data are written in ANISN format. L26P3S34 contains P0 to P3 matrices of the following materials:
Ti, H-1, C-12, N-14, O-16, F-19, Mg, Al-27, Si, Ar, P-31, S-32, Cr,  Mn-55, Co-59, Ni, Mo, Nb-93, Sn, Li-6, Li-7, B-10, B-11, He-4, Zr, Ba-138, Cl, Ta-181, Pu-239, Pu-240, U-235, Pb, Fe, Cu.
