Input (English): Initially the experimenters had assumed that the atoms were in an l = 1 state with their results lending support to the Bohr-Oppenheimer theory; however it was later determined that the atoms were in an l = 0 state, making the results at odds with both the Born-Oppenheimer theory and quantum mechanics. The accepted explanation of the results was first proposed by the graduate students Goudsmit and Uhlenbeck, though relativistic correctness would have to wait for Dirac. Classically, the expected result was a broad beam with a central peak, because an atoms magnetic moment may be oriented arbitrarily. Though it has been repeated many times with different beams, the original used a beam of silver atoms that passed between magnetic plates, which resulted in the beam splitting into 2 components. For ten points, name this experiment that demonstrated the existence and quantization of intrinsic angular momentum in the electron.
