Friday 10/23 Lecture: Why dpes M(s) Equal plus or minus 1/2?

Postby Sofia Lucido 3C » Fri Oct 23, 2020 9:06 pm

During today's lecture Dr. Lavelle talked about the spin magnetic quantum number being equal to either positive or negative 1/2 depending on if the electron was spinning up or down. I am curious to know why it is 1/2 and not a different number, what is the mathematical significance?

Thanks!

Great question!

Spin has half-integer values in order to discriminate fermions and bosons. The concept of half-integer spin stems from the Stern Gerlach experiment.

Look up fermions and bosons.
