Abstract :
Tesla-to-amper ratio giving the biggest error in /spl gamma/´p-low-field-experiment was determined using modified non-contacting method. Total error of 0.164 ppm was attained. Solenoid constant and /spl gamma/´p-value were corrected on magnetic susceptibility of air. The result is /spl gamma/´p=2.67515418 10/sup 8/ s/sup -1/ T/sup -1/ (Tesla BI-90) with total uncertainty of 0.18 ppm.
