Measuring Electron Spin

  1. Feb 16, 2012 #1
    Which experiment does show that electron has a spin of magnitude of [itex]\frac{1}{2}\hbar[/itex]?

    I guess, Stern–Gerlach experiment shows that electron has a kind of intrinsic spin; because of which, particle beam gets deflected in some specific way under the application of an external magnetic field. But does this experiment also show that this spin of electron has that specific magnitude?

    Would like to have web link or name of book, where the physical setup and execution & measurement procedure of such experiment can be found.

    Observence of fine splitting of the spectral lines in (eg) Hydrogen spectroscopy.
