A Monte Carlo calculation of the spatial distribution of resonance neutron capture across a O.387-in. diameter gold rod is compared with the corresponding measured distribution, obtained by activating small gold foils stacked across a diameter of a cadmium covered gold rod. The difference between the Monte Carlo calculation and the measurement is attributed to relatively unshielded capture at energies above 250 ev, the starting energy for neutrons in the Monte Carlo calculation.
