Abstract:

In an albedo effect experiment, the reaction rates of gold foils predicted by simulations were a few times bigger than the measurements. Theoretical analyses showed that the main reason of the difference comes from the gold’s resonance self-shielding effect on neutrons below 1 keV. Then, a new resonance self-shielding effect experiment was carried out and the experiment data agreed with the theoretical results. The thickness of the metal foil at low neutron’s energies can be recommended by the analytic method.
