The potassium atoms are Stern-Gerlach Experiment(SGE) , carried out in 1922, is considered as a canonical experiment that led us on the way to quantum mechanics[1]. In the famous experiment, Stern and Gerlach demonstrated In the Stern-Gerlach experiment, the ground state neutral atoms are deflected by a perpendicular magnetic field according to their value of spin.

A schematic of the Stern-Gerlach experiment is shown in Figure 1. 2018-06-01 · The Stern-Gerlach experiment has played an important role in our understanding of quantum behavior. We propose and analyze a modified version of this experiment where the magnetic field of the detector is in a quantum superposition, which may be experimentally realized using a superconducting flux qubit.

It was an attempt to prove the existence of "space quantization," the limitation of the direction of angular momentum to a few space directions, as hypothesized by Niels Bohr and Arnold Sommerfeld. This straightforward analogy is especially useful to understand Stern-Gerlach experiments that involve a sequence of Stern-Gerlach apparatuses with each one being rotated with respect to the next one, because they can be explained by using the same mathematical model of states and measurements like that of a sequence of calcite polarizers; i.e. essentially, by using Malus law. The classic Stern-Gerlach Experiment shows that atoms have a property called spin. Spin is a kind of intrinsic angular momentum, which has no classical counterpart. When the z-component of the spin is measured, one always gets one of two values: spin up or spin down. The Stern-Gerlach apparatus consists essentially of a magnet producing a non- uniform magnetic field.

In stern gerlach experiment

In the original experiment, Stern and Gerlach used silver atoms. These atoms have a magnetic north and south pole and generate a magnetic field around themselves. In the experiment … The purpose of this tutorial is to analyze the Stern-Gerlach experiment using matrix mechanics. The figure below is taken (and modified) from Thomas Engel's text, Quantum Chemistry & Spectroscopy . Silver atoms are deflected by an inhomogeneous magnetic field because of the two-valued magnetic moment associated with their unpaired 5s electron ([Kr]5s 1 4d 10 ). A closed shell has zero total angular momentum and therefore produces onla an extremely weak diamagnetic response - nothing you'd see in the Stern Gerlach experiment.
