Any of a class of particles, including photons, mesons, or alpha particles, that have integral spins and do not obey the exclusion principle, so that any number of identical particles may occupy the same quantum state.
[After Satyendra Nath Bose.]
(Atomic Physics) any of a group of elementary particles, such as a photon or pion, that has zero or integral spin and obeys the rules of Bose-Einstein statistics. Compare fermion
[C20: named after Satyendra Nath Bose; see -on]
any of a class of elementary particles not subject to the exclusion principle that have spins of zero or an integral number.
