What is Electron Spin? - Electron Spin Theory & Formulas - BYJU'S
As in classical theory, the electron spin theory describes the electron as a quantum particle instead of a simple sphere. The theory says that “the electron spin direction and its influence on certain properties like the atom’s magnetic properties”. The spin up and spin down directions correspond to the spinning in the “+z” or “–z” direction.

2023年10月22日 · Electron Spin or Spin Quantum Number is the fourth quantum number for electrons in atoms and molecules. Denoted as ms m s, the electron spin is constituted by either upward (ms = +1/2 m s = + 1 / 2) or downward (ms = −1/2 m s = − 1 / 2) arrows.
Electron Spin - HyperPhysics
Spin "up" and "down" allows two electrons for each set of spatial quantum numbers. An electron spin s = 1/2 is an intrinsic property of electrons. Electrons have intrinsic angular momentum characterized by quantum number 1/2. In the pattern of other quantized angular momenta, this gives total angular momentum

Due to electron spin, the Ag atoms act as tiny magnets as they pass through the magnetic field. These “magnets” have two possible orientations, which correspond to the spin-up and -down states of the electron. The magnetic field diverts the spin up atoms in one direction and the spin-down atoms in another direction.

These correspond to quantum states in which the spin component is pointing in the +z or −z directions respectively, and are often referred to as "spin up" and "spin down". For a spin- 3 / 2 particle, like a delta baryon, the possible values are + 3 / 2 , + 1 / 2 , − 1 / 2 , − 3 / 2 .

α≡ "spin up" β≡ "spin down" Spin eigenfunctions are orthonormal: ∫ α* αdσ= ∫ β*βdσ= 1 σ≡ spin variable ∫α*βdσ= ∫ β*αdσ= 0 Spin variable has no classical analog. Nevertheless, the angular momentum of the electron spin leads to a magnetic moment, similar to orbital angular momentum.
Definition of Electron Spin - Chemistry Dictionary
If the electron spins clockwise on its axis, it is described as spin-up; counterclockwise is spin-down. This is a convenient explanation, if not fully justifiable mathematically. The spin angular momentum associated with electron spin is independent of orbital angular momentum, which is associated with the electron's journey around the nucleus.

The paths of spin-up or spin-down electrons through the arrangement are different, but both spin orientations emerge undeflected. If we insert a beam block, only spin-up particles can pass. With the beam block in place, one half of the incident electrons will be stopped inside the apparatus, while the other half will emerge undeflected.
