Available in PDF, EPUB and Kindle. Book excerpt: An experiment whose object is to measure the energy dependence of helicity of positrons emitted from Ne-19 is described. The positron helicity is measured indirectly by transferring it to the annihilation-in-flight photons, whose transmission through a magnetized iron cylinder is dependent on their polarisation. The positron helicity therefore results in a difference of the counting rates for opposed directions of the magnetic field. The measured dependence of this asymmetry with pulseheight is compared with a computation which assumes the validity of the two component neutrino theory of beta decay and neglects the depolarisation of positrons. A good fit of theoretical curve to the experimental points is obtained for pulseheights larger than about 1.3 Mev. A strong disagreement is found in the pulseheight range between 0.75 and 1.0 Mev, where the experimental asymmetries are much lower than the prediction. The measurement of the asymmetry of bremsstrahlung produced in copper by electrons from a Sr-Y-90 source is used in order to measure the effective number of aligned electrons in the magnetised iron cylinder.

Book excerpt: uncertainties affecting the polarimeter system is presented including estimates, calculations, and measurements of all known effects. As a feasibility test of the polarimeter operation, the longitudinal polarization of positrons in ('22)Na decay was measured relative to ('68)Ga, which served as a "normalizing" source, with the result:
