摘要: Measurements were made to determine the longitudinal electron polarization of theβ−-decays Ca-45, Pm-147 and Tl-204. Theβ−-transition Co-60 served as a reference standard all measurements carried out relative it thus strongly reducing instrumental errors. The measuring principle is based on Mott-scattering technique with Mott-analyzer similar that van Klinken [1] Wien-filter for spin transformation from transverse. For each isotope several at different energies ranging 80–200 keV. In summary, not single deviation theoretical value -v/c was found.
