Circular polarization of external bremsstrahlung from beta emitters
The results of an investigation concerning the circular polarization- energy relation of the external bremsstrahlung radiation produced by beta rays from various beta emitters are reported. It was found that at the upper limit of the spectra the circular polarization of the EB quanta corresponds to a longitudinal polarization of beta rays equal to: -(1.05 plus or minus 0.04) v/ c (P/sup 32/; -(0.98 plus or minus 0.03) v/c Y/sup 90/); -(0.98 plus or minus 0.02) v/c (Tm/sup 170/). At the lower energy side of the spectra the circular polarization was found very high and larger than that estimated on the basis of present knowledge. Consideration is given of the attempts to ascertain how the events which occur before an EB quantum is radiated contribute to the measured polarization-energy relation.
