(n) (physics) statistical law obeyed by a system of particles whose wave function is not changed when two particles are interchanged (the Pauli exclusion principle does not apply)
prop. n. [ From physicists S. N. Bose, and Albert Einstein. ] (Physics) A law of statistical mechanics which is obeyed by a system of particles when interchange of two particles does not change the wave function. Contrasted to Fermi-Dirac statistics. See also boson. [ PJC ]
