BS>Neutron-spectrum measurements in several moderators were made with geometrical conditions approximating an infinite medium. The moderators studied were water, polyethylene, and benzene, and the absorbers dispersed in the moderators were boron, samarium, erbium, and gadolinium. The measurements are compared with predictions of the neutron spectra utilizing scattering models that take into consideration chemical binding. Measurements of scalar and angular neutron-energy spectra were made in a slab geometry water-moderated multiplying assembly at room temperature. The measured spectra are compared with DSN transport-theory calculations utilizing the Nelkin bound-hydrogen scattering model for water. (auth)
