摘要：

The proton gyromagnetic ratio in water has been measured by the low field method using atomic magnetic resonance in He-4, a multicurrent solenoid and an induction method for the dimensional measurement of the solenoid, The result for air and vacuum environment is gamma(p)' (low, air) = 2.67515451 x 10(8) s(-1) T-1 (0.18 x 10(-6)), gamma(p)' (low, vacuum) = 2.67515418 x 10(8) s(-1) T-1 (0.18 x 10(-6)), based on the adopted values KJ-90 = 483597.9 GHz/V, RK-90 = 25812.807 Ohm, and measured values gamma(4He)/gamma(p)' = 658.200556, gamma(4He) (air) = 1760.78819 x 10(8) s(-1) T-1 (0.18 x 10(-6), KJ-90, RK-90).
