  A new measurement of the differential cross section for neutron-proton scattering was performed at a neutron energy of MeV. The neutrons were scattered from a polyethylene foil and the associated recoil protons were observed. Data were taken at 6 angles between ° and ° in the centre-of-mass system.

The free neutron-proton elastic differential cross section has been measured at neutron beam energies of and MeV.. The experiment determined the angular distribution over the range 15°° (CM) in two segments, having the same overall normalization. The 15°° range was measured by detecting scattered neutrons in a scintillator and HWPC array. Normalization .

Elastic scattering cross-sections for light elements are more or less independent of neutron energy up to 1 MeV. For intermediate and heavy elements, the elastic cross-section is constant at low energy with some specifics at higher energy. A good approximation is, σs = const, for all elements, that are of importance. Fig 1.

Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron has a mass that is approximately 1/ that of the ered: J. J. Thomson ().
