But the reason for that is not that one electron is free and another is 
bound.  But that (IIUC) either the measured free electron and the measured 
bound electron had opposite spins to begin with, or, that the same electron 
has been measured before and after interacting with one, three, or so on
fitting photons (of a magnetic field applied to it), changing its spin from 
−½ to +½ or vice-versa as photons have absolute spin 1 and spin is a 
conserved quantity.  [The interesting thing about QM is that you cannot be 
sure which possibility applied due to the uncertainty principle.]

Also, I learned in the meantime that one must differentiate between spin
and iso(baric )spin.  The former quantum number, although being related to 
intrinsic angular momentum, is not related to a rotational velocity as e.g. 
the electron is a *point(-like)* particle (a point cannot rotate or, IOW, 
rotation of a point is indistinguishable from not rotating it); but it is a 
*magnetic* property (how that electron behaves in a magnetic field). The 
latter quantum number is not related to angular momentum at all, but merely 
observes similar math.
