Search For Anomalous n-p ScatteringAt 60 eV - 140 keV

摘要

A search for an anomalous n-p scattering from a polyethylene sample (CH2) at 8 finalenergies between 64 eV and 2.5 keV was carried out. The scattering intensities were compared tothat from a graphite (C) sample. The results were found to confirm our previous n-p results on H_2O at a final energy of 24.3 keV where no n-p scattering anomaly was observed. The presentresults refute all proposed models attempting to explain the occurrence of any n-p scatteringanomaly at keV neutron energies.
