Compound-Elastic Scattering of 4.2-Mev Neutrons in Lead

Abstract
Measurements of the differential elastic scattering cross sections of normal lead and radiolead (88% lead-206) for 4.2±0.1 Mev neutrons show a marked difference. Within experimental error this difference appears to be isotropic. It is concluded that the difference is due to compound-elastic scattering in lead-208.
