摘要：

The design and operation of a small angle Mott-Schwinger scattering fast neutron polarimeter of substantially improved efficiency is described. The advantages and disadvantages of such a polarimeter are discussed in relation to the more usual 4He scattering system. An account is given of the use of the polarimeter to determine the polarization of the neutrons emitted at 45° from the 2H(d, n)3He reaction for deuteron energies from 100 to 500 keV. The results are in excellent agreement with the most recent n-4He scattering measurements and of comparable statistical accuracy. Incidentially to these measurements, the total cross-section and the differential cross-section near to 0° were obtained for Pb for neutrons from 2.20 to 3.14 MeV. © 1979 North-Holland Publishing Co.
