Experimentally, the electron's magnetic moment is slightly larger than the Bohr magneton
. In the Ring Electron Model, it was impossible to explain the electron's anomalous magnetic moment.
 could be produced, because the very small number (e.g., ~[10.sup.-3] of neutrons) of the remaining electrons can be compensated by the Bohr magneton
, [mu] = e[??]/2[m.sub.e], which is ~ 1840 times larger than [[mu].sub.N].
where v is resonance frequency, h is Plank's constant, g is the g-factor (which is a constant = 2 for 1/2 spin), [beta] is the Bohr magneton
which is an electron magnetic dipole moment and H is the magnetic field.
When 1/2 of the solution was added, time recorder was started till the magneton

We would like to thank Magneton
from Russia for their help providing us with the magnets needed in this experiment.
The smallest mass is probably the rest mass of an electron, referred to in the following definition: One of the constituent elementary particles of an atom being a charge of negative electricity equal to about 1.602 x 10 exp--19 coulomb, having a mass when at rest of about 9.109 x 10 exp--28 gram of 1/1837 that of a proton, being the least massive known charged particle, and having a magnetic moment of about 1 Bohr magneton
associated with its one half quantum unit of spin
where [A.sub.S] and [A.sub.D] are the dipole hyperfine constants, [g.sub.J](S) and [g.sub.J](D) are the electronic g-factors, [g'.sub.I] is the nuclear g-factor, h is the Planck constant, and [[micro].sub.B] is the Bohr magneton
. All of the parameters entering [H'.sub.S] and [H'.sub.D] are known from experiments, although a more accurate measurement of [g.sub.J](D) would be useful.
