    "abstract": "We calculate the Wigner distribution function for the Calogero-Sutherland\nsystem which consists of harmonic and inverse-square interactions. The Wigner\ndistribution function is separated out into two parts corresponding to the\nrelative and center-of-mass motions. A general expression for the relative\nWigner function is obtained in terms of the Laguerre polynomials by introducing\na new identity between Hermite and Laguerre polynomials.",
