Laboratory scattering experiments undertaken at the 6 MV<br />
Van de Graaff accelerator <strong>of</strong> the National Accelerator Centre, South Africa.<br />
• <strong>Neutron</strong> energy multiplexed between 7.5 MeV and 6.8 MeV by rotating<br />
a 11µm Havar foil in and out <strong>of</strong> the 4.5 MeV deuteron beam.<br />
• Pulse shape discrimination on all NE213 detectors.<br />
• Pulse height and time-<strong>of</strong>-flight information measured for small monoelemental<br />
samples, as well <strong>of</strong> compounds <strong>of</strong> known and “unknown”<br />
chemical composition.
