| Popis: | SEVERAL authors1,2 have measured the angular distribution of the particles produced in the D—D reaction as a function of bombarding energy in the range 100–400 keV. A theoretical fit to the observations demonstrates the possibility of a strong spin-orbit coupling in the interaction3. This coupling may produce polarization of the outgoing protons4. The polarization can be detected by observing the azi-muthal angular distribution of D—D particles scattered by nuclei in a process involving spin-orbit coupling. An azimuthal anisotropy would be proof of the polarization. Such an anisotropy has been demonstrated in a double-scattering experiment for protons of 3-meV. energy scattered by helium5. This provides a valuable analyser for the polarized proton. It was therefore decided to use this method in the search for a polarization of the protons produced in the D—D reaction. A previous attempt to detect polarization of the neutrons by scattering on carbon was vitiated by the background of neutrons produced by scattered deuterons in the accelerator tube. |
