Notizen: Abstract Assuming theV-A theory, fully polarized neutrinos, and lepton conservation, best values of the vector and axial vector coupling constants are deduced from all available data on neutron decay and from theft- values of14O,26mAl and34C1. Special consideration is given to the treatment of errors and to radiative corrections. For the determination of the coupling constantratio, radiative corrections are, at present, unimportant. We find ¦GA/GV¦=1.250 + 0.009 with a phase angle φ=(181.1±1.3)0. From the weighted mean ℱt-value, including charge dependent and “outer” radiative corrections, we find an effective coupling constant G′V=(1.413±0.002)x 1049erg cm3. The error is mainly due to the uncertainty of charge dependent corrections.
