STERN-GERLACH EXPERIMENT In 1922 Otto Stern and Walther Gerlach performed a seminal experiment in the history of quantum mechanics. In its simplest form, the experiment consisted of an oven that produced a beam of neu-tral atoms, a region of space with an inhomogeneous magnetic eld, and a detector for the atoms, as depicted in Fig. 1.1. Stern ...
The Stern-Gerlach experiment is notoriously counter-intuitive. The official theory is that the spin of a fermion remains always aligned with the magnetic field. Its directions are thus quantized: It can only be spin up or down. But that theory is based on mathematical errors in the way it (mis)treats spinors and group theory.
Das Experiment, das Otto Stern und Walther Gerlach 1922 in Frankfurt durchführten, sollte die Frage klären, ob der Drehimpuls von Atomen eine Richtungsquantelung aufweist. Zur damaligen Zeit war das Bohrsche Atommodell noch in aller Munde. Die Quantenmechanik entwickelte sich gerade erst. Phänomene wie der normale und der anormaler Zeeman ...
26. Jan. 2023 · View PDF Abstract: The following is a translation of the paper by Walther Gerlach and Otto Stern that reported the first evidence for the quantisation of atoms in a magnetic field. The atoms have quantum states corresponding to a limited number of possible angles between the directions of the angular momenta of the atoms and the magnetic field ...
Figure 5–3 (a) shows a drawing of the “modified Stern-Gerlach apparatus” we would like to use. It consists of a sequence of three high-gradient magnets. The first one (on the left) is just the usual Stern-Gerlach magnet and splits the incoming beam of spin-one particles into three separate beams.

The Stern-Gerlach experiment was initially regarded as a crucial test between the classical theory of the atom and the Bohr-Sommerfeld theory. In a sense it was, because it showed clearly that spatial quantization existed, a phenomenon that could be accommodated only within a quantum mechanical theory. It decided between the two classes of theories, the classical and the quantum mechanical ...
