The Magnetic Moment of the Proton

The Stern–Gerlach Phenomenon According to Classical Electrodynamics

“…(B) Beam profiles (intensity in arbitrary units) showing the magnetic field deflection of a beam of HD molecules produced by an oven at 90 K (see ref. [24]). The experimental data were used to measure the magnetic moment of the proton (giromagnetic factor g = 5.4).…”

“…where we have used (24), (25), (26) and (27). The constant ξ is the efficiency of the detection method and τ is the time interval of the experiment (8 hours without interruption [16]).…”

Molecular Beam Technique

“…The oven material should not react chemically or alloy itself with the molecular beam substance. For cesium beams (25), for instance, the oven had to be made of monel, although the operating temperature was as low as 175'C. It is also essential that the charge in the oven has a surface which is large compared to the area of the oven slit, because the rate of evaporation should be much larger than the rate of elusion through the aperture given by Eq.…”

“…The heater (37) consists of a glass tube, which is platinized by the burning in of several coatings of "liquid bright platinum" solution, ' and should have a resistance of a few ohms. A design' used recently for cesium (25) is shown in Fig. 5.…”

Study of Generalized Parton Distributions and Deeply Virtual Compton Scattering on the nucleon with the CLAS and CLAS12 detectors at the Jefferson Laboratory

“…We know from Stern and collaborators experiment (magnetic deection of molecular beam employing H 2 , performed in 1932 [EOO37]) that the proton has a magnetic moment that is approximately a factor 2.79 (measured 2.46 in 1932) larger than predicted for a Dirac particle. The consequence is that the proton can not be considered as a point-like spin-1 2 particle.…”
