Angular Distribution of Neutrons Scattered from Aluminum, Iron, and Lead

Abstract
The differential cross sections for the scattering of 3.7-Mev neutrons from aluminum, iron, and lead have been measured in a ring geometry using a molded Lucite-zinc sulfide button as a detector. The measurements were taken over an angular range of 127 degrees between 13 degrees and 140 degrees with an angular resolution better than ±10 degrees. Effects due to higher-order scattering in the scatterer were removed by extrapolation.
