Abstract

We present an experimental investigation of thermal neutron energy spectra produced by lead and bismuth hydroxides (Pb(OH)₂, and Bi(OH) ₃). The experimental energy spectra are compared with a thermal neutron energy spectrum produced by water measured in the same geometry. We developed an MCNPX geometry model designed to help with the interpretation of the experimental data. We demonstrate a very good reproduction of the experimental thermal neutron energy spectrum produced by the water moderator in our tightly coupled geometry. We study our experimental results for Pb(OH) ₂ and Bi(OH)₃ using thermal neutron scattering kernels for hydrogen, bismuth, and lead.
