Spin angular momentum of nucleus

WebSz is the z-component of spin angular momentum and ms is the spin projection quantum number. For electrons, s can only be 1/2, and ms can be either +1/2 or –1/2. Spin projection ms = +1/2 is referred to as spin up, whereas ms = −1/2 is called spin down. These are illustrated in Figure 3. WebMar 18, 2024 · To distinguish the spin angular momentum from the orbital, we designate the quantum numbers as s and m s, in place of ℓ and m. For the electron, the quantum number s always has the value 1 2, while m s can have one of two values, ± 1 2. The electron is said to be an elementary particle of spin 1 2.
