The time-of-flight technique is used on a small-angle neutron scattering instrument to separate the energies of the scattered neutrons, in order to determine the origin of the temperature-dependent scattering observed from silicon atQ> ∼0.1 Å−1. A quantitative analysis of the results in comparison with the phonon dispersion curves, determined by Dolling using a triple-axis neutron spectrometer, shows that the temperature-dependent scattering can be understood in terms of Umklapp processes whereby neutrons gain energy from phonons.

The spin-flip probability S(θ) in the inelastic scattering of unpolarized 15.0-MeV neutrons to the first 2+ state in 12C has been determined at θ = 140° (lab.) by measuring the scattered neutrons in coincidence with the subsequent 4.44- MeV deexcitation γ-rays emitted normal to the scattering plane. Time-of-flight technique with carbon recoil detection in a plastic scintillator has been used. The neutron spin-flip probability is S = 0.21±0.06.
