Apparently we have a difference of opinion here - not sure if the differences can be readily resolved. If the target does rotate, then the energy for the rotation has to come from somewhere - obviously the electrons do not lose some of their "spin energy" to the target, i.e., the absorbed...

Thanks for being skeptical - I am wondering how true this statement is: "When a beam of spin polarized electrons is absorbed by a target, then the target will start to rotate," which is stated in such an off hand manner in Robert Oerter's "The Theory of Almost Everything," I thought perhaps it...

As an addendum, which I should have brought up earlier, is the conservation of energy in this process: the electron's spin imparts energy to the target by causing the target to rotate, yet the magnitude of the electron's spin does not decrease or lose energy, the electron's spin only changes...

No, here I am specifically referring to electrons, or fermions in general. I suspect more high profile experiments have been done with spin polarized photons causing a target to rotate, but the same holds true for a spin polarized electron beam. The phenomenon with a photon beam seems to make...

Hey, I am new to the forum, and would certainly appreciate help in understanding spin - although I realize that perhaps no one really understands spin. If a beam of spin polarized electrons are absorbed in a target, then the target will start to rotate. This kind of makes sense on a...
