Title: Scattering of 64 eV to 3 keV Neutrons from Polyethylene and Graphite and the Coherence Length Problem

Abstract

We measured the neutron scattering intensity ratios from polyethylene (CH{sub 2}) relative to graphite (C) at several discrete final energies, of narrow widths ({approx}3 eV) between 64 eV and 3 keV. The final energies were selected using a {sup 238}U filter. This experiment was carried out to search for any anomaly in the n-p scattered intensities from CH{sub 2} caused by the neutron coherence length. The scattered intensity ratios were found to conform to conventional expectations and no anomaly was observed.
