Description

The experimental program outlined is directed toward the utilization of the ac Josephson effect to maintain surveillance of the unit of emf in Canada. Preliminary results indicate a weighted mean value of 2e/h=483 593.0 +- 0.2 (0.4 ppm) GHz/V( NRC(73)) which is, at present, not precise enough to detect the small drifts normally encountered in the mean value of the standard cell group upon which V(NRC) is based
