Determination of the tesla-to-ampere ratio for the KRISS/VNIIM /spl gamma/'/sub P/-experiment

Tesla-to-ampere ratio giving the largest error in the /spl gamma/'/sub P/-low-field-experiment has been determined using a modified noncontacting method. The total uncertainty of 0.164/spl times/10/sup -6/ has been attained. The constant of a solenoid and the /spl gamma/'/sub P/-value have been corrected for magnetic susceptibility of air. The result is /spl gamma/'/sub P/=2.675 154 18/spl times/10/sup 8/ s/sup -1/ T/sup -1/ (Tesla BI-90) with the total uncertainty of 0.18/spl times/10/sup -6/.
