Observing the spin of free electrons in action(Stern-Gerlach experiment by free electrons)

TL;DR

This paper demonstrates the feasibility of observing the spin of free electrons using a high vacuum lamp and a sharp magnet, challenging previous assumptions about the experiment's impossibility due to magnetic field gradient limitations.

Contribution

It introduces a practical method to observe free electron spin using accessible magnetic field gradients and specific technical setups, previously considered unfeasible.

Findings

Successful observation of free electron spin in a controlled setup

High magnetic field gradient achievable with a sharp magnet and voltage adjustment

No need for extremely strong magnetic fields or time-varying fields

Abstract

Stern-Gerlach experiment by free electron is very important experiment because it answered some questions that remain unanswered for almost a century. Bohr and Pauli considered its objective observation as impossible while some other scientists considered such observation as possible. The experiment on free electrons has not been conducted so far because the high magnetic field gradient predicted there was thought as impossible to generate. This paper proves that it is not only possible but also observable using a high vacuum lamp which is deionized well. To obtain a high magnetic field gradient, it is not necessary to have a very strong magnetic field and it is possible to observe the phenomenon using a very sharp pointed magnet and adjusting the voltage in a certain distance from free electron beams. that objective observation requires your consideration of some technical points simultaneously.In this experiment, no electric field and no magnetic field does not change with time.
