    "abstract": "A unified semiclassical time propagator is used to calculate the\nsemiclassical time-correlation function in three cartesian dimensions for a\nparticle moving in an attractive Coulomb potential. It is demonstrated that\nunder these conditions the singularity of the potential does not cause any\ndifficulties and the Coulomb interaction can be treated as any other\nnon-singular potential. Moreover, by virtue of our three-dimensional\ncalculation, we can explain the discrepancies between previous semiclassical\nand quantum results obtained for the one-dimensional radial Coulomb problem.",
