Circular Polarization of External Bremsstrahlung Produced by Beta Rays

1958

For energies smaller than 600 kev, the polarization was previously measured using forward scattering from magnetized iron, but a quantitative comparison was not performed. Computations were done for monoenergetic electrons falling on a thin absorber, whereas in all experiments the whole beta spectruan and thick absorbers were used. It is shown thnt even in this case a comparison with theory is possible as the diffusion of the electrons in the absorber has practically no influence on the polarization. Strong dependence of the circular polarization on the atomic number of the absorber is investigated. (W.D.M.)

Messung der zirkularen Polarisation der inneren und �u�eren Bremsstrahlung

1961

The polarisation of the internal bremsstrahlung γ's was detected by the Compton-forward-scattering with polarised electrons for three differentβ-decays: 1. for the allowed transition (P32), 2. for the unique forbidden transition (Sr90+Y90), and 3. for the forbidden transition with forbidden spectrum (Bi210=RaE). The detected polarisation values of P32 and (Sr90+Y90) agree with the theoretical values for the allowed transitions. The detected polarisation values for Bi210 are smaller than the theoretical values of the allowedβ-transition by a factor of 0.62±0.08.
