Exploring Electron Spin: The Stern-Gerlach Experiment and its Implications

Click For Summary
SUMMARY

The Stern-Gerlach experiment definitively demonstrates that electrons possess an intrinsic spin of magnitude \(\frac{1}{2}\hbar\). This experiment illustrates how a particle beam is deflected in specific directions when subjected to an external magnetic field, confirming the quantized nature of electron spin. Additionally, the fine splitting of spectral lines in hydrogen spectroscopy serves as a practical application of these principles, showcasing the implications of electron spin in quantum mechanics.

Which experiment does show that electron has a spin of magnitude of \frac{1}{2}\hbar?

I guess, Stern–Gerlach experiment shows that electron has a kind of intrinsic spin; because of which, particle beam gets deflected in some specific way under the application of an external magnetic field. But does this experiment also show that this spin of electron has that specific magnitude?

Would like to have web link or name of book, where the physical setup and execution & measurement procedure of such experiment can be found.
