EXCLUSION STATISTICS FOR NON-ABELIAN QUANTUM HALL STATES

We determine the exclusion statistics properties of the fundamental ed ge quasiparticles over a specific v= 1/2 non-Abelian quantum Hall stat e known as the q = 2 Pfaffian state. The fundamental excitations are t he edge electrons of charge -e and the edge quasiholes of charge +e/4. We explicitly determine thermodynamic distribution functions and esta blish a duality which generalizes the duality for fractional exclusion statistics as described by F. D. M. Haldane.
