Definition of half-integer
- Particles whose spin is a half-integer of h, on the other hand, are fermions satisfying the Pauli exclusion principle; no two particles can have the same state.

- All the particles that we like to think of as “real” particles, like protons, neutrons and electrons, have spin which is half-integral—1/2, 3/2, 5/2 and so on.
