Measurement of the proton moment in absolute units

Year: 1950

Type: article

Abstract: By measuring the absolute value of the magnetic fi eld a nd t he frequcncy requ ircd for nuclear resonance absorption in a water sample, the gyro magnctic ratio of t hc proton has been d etermined to be 'Y p = (2.67528± 0.00006) X 10 4 sec-1 gauss-I.Us in g this valu c with P lanck's constant, the valu e of the magnetic momcnt of the proton in a bsolutc units becomes }1op = (1.4100 ± 0.0002) X 10-23 dyne cm/gauss.A com bin ation of our resul t with recent meas urements of the proton momcnt in Bohr magnetons gives a value of e/ m = (1.75890± 0.00005) X 10 7 em u gram-I.
