Abstract
The ratio of the longitudinal polarization values of90Y and32P was measured at two energies by the method of Møller scattering. The results obtained areP(90Y)/P(32P)=0.992±0.036 at 0.725 MeV electron energy andP(90Y)/P(32P)=0.984±0.030 at 1.0 MeV. For the decay of90Y, polarization- and spectrum shape measurements are discussed in the framework of a formfactor coefficient analysis.
