The simplest Stern-Gerlach spin-1 transition is the +S -> +T -> +S transition. The expression defines(adsbygoogle = window.adsbygoogle || []).push({}); two events:

1) Polarization event of the +S state when passing to the +T state, +S -> +T, from the field free region to the field/gradient volume of the Stern-Gerlach T segment. Here we arbitrarily select the +T state as the polarized state.

2) Depolarization event of the +T state to the +S state as, +T - > +S state, when passing from the field/gradient volume of the SG segment to the +S state in the field free region (also force free region).

"+S" means 'up' motion in an S SG segment where the field/gradient is oriented 'up' wrt the lab frame (S means 'parallel to the Z-axis', + means 'up' along S.) A T segment is rotated pi/24 (the field gradient direction) radians around the direction of motion of the spin-1 particle and is obstruction free. The S segment producing the +S state has the center and lower transition channels blocked resulting in a loss of 2/3 of the input spin-1 particle stream into the S segment.

In general, all spin-1 particles entering the T segment and polarized to any allowed T state, pass through the T segment (we chose the +T as the polarized state), exiting in the prepolarized spin-1 +S state.

The +S -> +T event orients the S+ spin vector to the +T state direction, say pi/24 radians, when the particle enters the field/gradient region of the T segment from the field free region. The +T -> +S event reorients the +T state to the +S state. As compass needles find north with the force of the earth's magnetic field, the +S state is recovered when transitioning from the field gradient region in the T segment tothe field free region.The process as described is experimentally 100% reproducible and is equivalent to the description of an inertial frame..

Therefore, the +T state must be +T = +T(00[+S]) where 00[+S] are those unobserved elements of the +S state that. As this reformation is necessarily the physical reorientation of the spin vector a force is necessarily present. As there is no observed source of the reforming force, this force is definitionally nonlocal.guarantees the reformation of the +S state

The physical reorientation of the spin vector process is, therefore,intrinsicto the Spin-1 particle state transition process - better than mechanical or laser driven gyroscopes? Prolly.

What does QM Theory predictin the more general S ->T -> S transition?. Feynman ("Lectures on Physics" Vol III CH 5) tells us that the result is as if the T segment "were not present". This is verified by experimental results. Yet, Feynman tells us naught about the +S state reforming process. He enters the quantum mechanically defined foofoo land of 'interference amplitude'.

Block the lower and middle T segment channels and one always observes a +T particle exiting the T segment with a loss of the 2/3 of the +S state input particles to the T segment (see description above re "+S" state production).

As used here, "observed" means physically observed directly, or inferentially, as opposed to "observed" mathematically.
