Popis: The half-life of the super-allowed β - decay of 14O has been measured to be 70.623±0.053 s. The 14O was produced via the reaction 12C(13He,n)14O, and the decay was uniquely isolated using a triple-coincidence detection system. A novel digitisation technique, where every pulse was digitally recorded, guaranteed the integrity of the analysis. The half-life value was used to test the Conserved-Vector-Current (CVC) hypothesis, and thus indirectly the Standard Model.
