Elastic Scattering of 3.7-Mev Neutrons from S, Fe, Co, Ni, Cu, and Zn

Abstract

The differential cross section for the elastic scattering of 3.7-Mev neutrons from sulfur, iron, cobalt, nickel, copper, and zinc has been measured in a ring geometry using a modified Bonner-type scintillation detector. The measurements were taken over an angular range between 10° and 160°. Angular resolution effects have been removed by a suitable iterative procedure. Multiple-scattering effects have been removed by an approximate analytical treatment.

“…The quantities 0)2 and 0)3 were obtained by linear extrapolation to 1.49 and 0.61, respectively, at 3.7 MeV. This was based on data in [17] for sulphur. Total scattering cross sections were obtained by subtracting the inelastic-scattering cross sections of [18] from the total cross-section data.…”
