Abstract

We have measured the beta-decay branching ratio for the transition from Na21 to the first excited state of Ne21. A recently published test of the standard model, which was based on a measurement of the βν correlation in the decay of Na21, depended on this branching ratio. However, until now only relatively imprecise (and, in some cases, contradictory) values existed for it. Our new result, 4.74(4)%, reduces but does not remove the reported discrepancy with the standard model.
