Abstract

Precise observation of the ratio PFPGT 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 PFPGT=0.986±0.038. Resulting bounds, being comparable to those from existing muon polarization experiments, are limited by statistics. Precision of order 103 or better may be anticipated with an extended system.
