Abstract

Abstract The Fermi approximation and all higher order corrections are derived for the cross section for thermal neutron scattering from aggregates of atoms. The first order correction is shown to reduce to the result obtained by Lippmann and Schwinger in the special case that the scatterer is a single bound proton. The magnitude of the correction is estimated for an arbitrary number of scattering atoms, and it is shown to be approximately proportional to the inverse of the separation between atoms.
