The General Atomic Neutron Velocity Selector has been used to study the details of neutron scattering in reactor-grade graphite. The scattering into various angular directions between 30 and 120° has been studied for incident neutrons with energies ranging up to 0.611 eV. The energy-transfer cross sections, corrected for plural scattering effects, have been evaluated to provide data in regions of large energy and momentum transfers not previously available and not readily accessible to experimenters using a reactor as a source of neutrons. The results are quite definitive and, when compared to the best available theory, indicate some regions of good agreement and some regions where a more complete theoretical treatment would be useful.
