    "abstract": "The Gaussian Wave-Packet phase-space representation is used to show that the\nexpansion in powers of $\\hbar$ of the quantum Liouville propagator leads, in\nthe zeroth order term, to results close to those obtained in the statistical\nquasiclassical method of Lee and Scully in the Weyl-Wigner picture. It is also\nverified that propagating the Wigner distribution along the classical\ntrajectories the amount of error is less than that coming from propagating the\nGaussian distribution along classical trajectories.",
