CVI. The inelastic scattering of fast neutrons

Abstract

Abstract An anthracene scintillation counter has been used as a spectrometer to measure the energy distribution of initially monokinetic neutrons scattered from iron and aluminium. In each case discrete groups of neutrons with reduced energy were found, showing that the scattering nucleus was being raised to its excited states. The differential cross section for scattering through 97° has been measured for the various processes.
