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