Total Cross Section Measurements with Cold Neutrons on Solid and Powder Samples and on Hydrogen Containing Compounds

Abstract

Transmission measurements with cold neutrons of mean energy of 0.57 meV on solid and powder samples were performed to deduce the inelastic scattering cross sections σ_inel and the absorption cross sections σ_γ for 43 chemical elements and 27 of their isotopes. The Debye-temperature Θ, could be deduced from measurements. From similar experiments on water, alcohole and carbon hydrogen compounds the proton scattering cross section for cold neutrons was determined.
