Following the definition of Haldane's exclusion statistics, we proposea new and simple representation of the spectrum and the state countingof the quantum Calogero model. We show that N non-interactingparticles with statistical interactions confined in an externalharmonic well give exactly the same energy spectrum and the samedegeneracy as those of the N-particle quantum Calogero model. We alsoshow that this picture exactly corresponds to the generalized idealgas, which was introduced by Bernard and Wu.
