One of the stronger arguments against the theoretical model of the neutron performed by the structure n=p+e is the neutron?s spin, which is 1/2, because from the concepts of Quantum Mechanics a structure p+e would have to have an entire spin, but the experiments have shown that the neutron?s spin is 1/2. However, I argue that the structure n=p+e must be analyzed from two considerations, as follows:
- First of all, we must consider that spin is not a clear concept in Physics.
- As the theorist does not know what the electron?s spin actually is, and before trying to understand what happens with the electron?s spin in the structure n=p+e it is indispensable to get a comprehensive notion about what the spin actually is.
Herein we will analyze step by step the arguments that led to the conclusion about the existence of the electron?s spin. Furthermore, as the author already has proposed in his model for a new hydrogen atom[1] where the electron moves through the helical trajectory, here we will analyze the Stern-Gerlach experiment by considering the electron?s helical trajectory in the hydrogen atom, which has been used by Phipps and Taylor when they made an experiment by using the Stern-Gerlach technique.
