Isn't spin in the sense of describing the 3D-rotation of a hypothetical
magnetic dipole just the first best guess explaining experiments like
that by Otto Stern and Walther Gerlach? Even if this guess might be
correct, prudent businessmen prefer demanding at least three competing
offers in case of important projects. Let's accept Arnold Neumaier's
abstract description like the first one. Being ignorant of quantum
physics, I will nonetheless also try and suggest what I consider a first
crazy approach to an alternative idea. I imagine an electron having a
standing wave structure like sinc(kr). The frequency doublet and beam
splitting might possibly result from interaction of the corresponding
inward and outward spatial waves with the external magnetic field, no
matter that the external field is so far considered a vortex of constant
strength B.
