How is spin measured experimentally ?

  1. Feb 11, 2014 #1
    Hi,

    this probably has been answered somewhere here already, but I was unable to find it.
    Could someone explain how the spin of a particle is actually measured in an experiment ? Most interesting to me is how the 3d spin vector for 1/2 spin particles is determined experimentally.

    Cheers.

    It is impossible to measure a 3d spin vector - i.e. all three components - of anything.

    thank you. the Stern-Gerlach Experiment was helpful indeed.
