“…polarization measurements can help to determine these formfactors or, at least ratios of them thus telling us something about the decaying nucleus itself. In the past many measurements also yielded deviations from -v/c for allowed and first-forbidden decays [4,6,12,13] which to our opinion are due to instrumental effects, wrong analyzing-powers and depolarization in the sources. Furthermore, the polarization of a second-forbidden transition has never been measured, besides one not very accurate measurement at the high energy of 780 keV for 137Cs [14].…”
