Superallowed 0 → 0 nuclear beta decay provides a direct measure of the weak vector coupling constant, GV. We survey current world data on the nine accurately determined transitions of this type, which range from the decay of C to that of Co, and demonstrate that the results confirm conservation of the weak vector current (CVC) but differ at the 98… (More)
