A comparison is reported of measured and Monte Carlo calculated spatial distributions of U/sup 238/ resonance neutron capture in a 0.387-in. diameter uranium metal rod in a hexagonal light-water moderated lattice with rod centerto- center spacing of 0.567 in. The following calculational results were obtained: (1) the fraction of neutrons started at 10 kev which are captured in the rod above 3 ev; (2) the fraction of total capture in each of the twenty rings across the rod; and (3) the fraction of total capture in each of 16 energy intervals for each of the two main regions of the rod. Curves are given which show the comparison of the adjusted Monte Carlo calculation with the measured spatial distribution. These results indicate that the code used is quite capable of giving a detailed prediction of the spatial distribution of resonance neutron capture across the rod diameter. It is significant to note that the agreement between experiment and calculation gives added justification to the treatment of the higher energy resonances. (B.O.G.)
