Nigel— Spin, angular momentum and magnetic moment are closely related in particles and entire coherent systems of particles IMO. Angular momentum is a vector quantity and can be aligned in a specific direction, if there is a magnetic moment associated with the entity with the angular momentum. Electrons are identical examples of such an entity.
Regarding the experiment that destroyed the spin in a non-measured axis, it would seem to me that the manipulation of the subject (measured) particle depended upon its magnetic moment being aligned with a magnetic field and associated angular momentum such that there was no way to determine spin along the other axes. Philippe Hatt’s theory of the composition and parameters of neutrons and protons—charge, mass and magnetic moment---as a system of positons and electrons is instructive. His predictions of these parameters is “dead nuts on” with respect to existing experimental accuracy. (No quarks involved or other virtual particles, only real particles.)

In what sense has the state of the particles spin been changed and what mediates the change. Can it be thought of as in terms of a virtual photon exchange?. I assume that overall there must be conservation of spin, so in what sense has the spin state of the rest of the system been changed? Nigel
