Radioactive Decay and Measurement Techniques

The volt has been determined to high accuracy using a liquid electrometer. The representation of the volt maintained by the Josephson effect using the value of 2 e/h = 483.594 THz/V recommended by the Consultative Committee on Electricity of the International Committee of Weights and Measures in 1972 has been measured to be smaller than the SI volt by (8.09 ± 0.27) ppm. This implies that the SI value of 2 e/h is (483.59791 ± 0.00013) THz/V. Full experimental details are given.
