Experimental study reveals differential elastic scattering cross sections of 14.5-MeV neutrons across seven complex nuclei, providing high-resolution angular data on nuclear interactions.
New measurements of the differential elastic scattering cross sections of C, Al, Fe, Cu, Sn, Pb, and U for 14.5-Mev neutrons are reported. For Fe, Cu, Sn, and Pb the angular range from 5^∘{} to 150^∘{} was investigated with ±{}1^∘{} to ±{}3^∘{} angular resolution. For the other elements a smaller angular range was investigated. Particular effort was devoted to the problem of discriminating against inelastically scattered neutrons and methods were developed which provided an experimental energy resolution of {~}500 kev. Limited differential cross section data for inelastically scattered neutrons of energy greater than 9 Mev are also presented for Fe, Cu, Sn, and Pb.
