Precise observation of the ratio PF/PGT of beta polarizations for Fermi and Gamow-Teller decays can provide stringent constraints on electroweak models. The result of a first measurement, with a Bhabha polarimeter of novel design, is PF/PGT=0.986 ± 0.038. Resulting bounds, being comparable to those from existing muon polarization experiments, are limited by statistics. Precision of order 10-3 or better may be anticipated with an extended system
