Definition of exclusion principle in US English:

exclusion principle

(also Pauli exclusion principle)


    • ‘Pauli was awarded the Nobel Prize in 1945 for his: -… decisive contribution through his discovery in 1925 of a new law of Nature, the exclusion principle or Pauli principle.’
    • ‘In 1925, Wolfgang Pauli gave physics his exclusion principle as a way to explain the arrangement of electrons in an atom.’
    • ‘Electrons can't violate the exclusion principle!’
    • ‘Fermions are the particles that exhibit half-integer spin and satisfy the Pauli exclusion principle, while bosons exhibit integer spin and are not limited by the exclusion principle.’
    • ‘On this side, which is explored by applying higher magnetic-field values, long-range pairing between atoms is possible due to the combined effect of interactions and the exclusion principle.’
    • ‘As Wolfgang Pauli's famous exclusion principle states, identical fermions cannot occupy the same quantum state at the same time.’
    • ‘Surely trying to teach the physical nature of even the simplest chemical bonds - exclusion principle, wave interference - needs to be done by the physics teacher.’
    • ‘Addition of this exclusion principle to the then current theory of atomic structure enabled many additional predictions to be made about atomic spectra and chemical combination.’
    • ‘The quantum exclusion principle undergirds the fixed structure of the periodic table.’
    • ‘In 1924, Pauli formulated his famous exclusion principle, according to which no two electrons in an atom may have all four identical quantum numbers.’
