Energy-dependent point cross sections were recorded over the range from 0.005 to 2.5 ev for the heavy elements Th, U/sup 233/,U/sup 234/, U/sup 235/, U/ sup 236/,Np/sup 2/ s/sup 39/,Pu/sup 239/,Pu/sup 240/, Pu/sup 241/ and Pu/sup 2 / 4>s/sup 2/; for the specific fission products Mo/sup 95/, Tc/sup 99/, Rh/sup 103/ , Cd/sup 113/, Xe/sup 131/,Xe/sup 135/,Cs/sup 133/,Cs/sup 135/, Nd/sup 1/ /sup 43/ ,Nd/sup 145/,Pm/sup 147/,Sm/sup 149/ Sm/sup 151/ >s, Sm/sup 152/,Eu/sup 153/,Gd/ sup 155/, and Gd/sup 157/; an d for the fission-product aggregates for U/sup 233/ ,U/sup 235/, and Pu/sup 239/. The poi nt cross sections are given in a form suitable for use with General Atomic's thermalization codes. Examples of thermal spectra and associated average cross sections were recorded for C: U/sup 235/ atom ratios of 2,819, 5,000, 7,500, and 10,000 for various graphite temperatures. (auth)
