{wiki=Stern–Gerlach_experiment}
The Stern-Gerlach experiment is a fundamental experiment in quantum mechanics that demonstrates the quantization of angular momentum and the existence of quantum spin. It was first conducted by Otto Stern and Walther Gerlach in 1922. \#\#\# Setup: The experiment involves the following components: 1. **Beam of Silver Atoms**: A narrow beam of neutral silver atoms is used. Silver atoms have a single unpaired electron in their outer shell, leading to a net spin and magnetic moment.
