(also Pauli's exclusion principle)
- The assertion that no two fermions can have the same quantum number.More example sentences
- Fermions obey the Pauli exclusion principle, which means that two of them cannot occupy the same quantum state.
- For electrons, the Pauli exclusion principle paradoxically leads to an effective attraction that balances the particles' electrostatic repulsion at short distances.
- In addition to electrons, the Pauli exclusion principle applies to all sub-atomic particles with half-integral spins, known as fermions, such as neutrons and protons.
1920s: named after W. Pauli (see Pauli, Wolfgang).
