Recent Results on the Branching Ratio in the Beta Decay of Oxygen-14

As one of the most allowed beta decays, and as a member of the A=14 isospin triplet, the 0+ to 0+ beta decay of oxygen-14 plays an important role in tests of the weak interaction. We have been involved in high precision measurements of the spectral shape and of the branching ratio, which are important for such tests. Preliminary analysis of the latest branching ratio data will be presented.
