Boral is a material composed of 50 % A1, 40 % B, and 10 % C by weight. Its density is 2.56 g/cm³. A beam of 0.025-eV neutrons with the intensity of 5 *10° neutrons/(cm² xs) strikes a target of 2.5 cm² in area made of the boral. Calculate the atom densities of AI, B, and C in boral. Calculate the macroscopic cross-sections S₂, S., and S, for boral at the neutron energy 0.025 eV. How thick must the boral target be in order to reduce the intensity of such a neutron beam by a factor of 7 ? Boral is a material composed of 50 % A1, 40 % B, and 10 % C by weight.
