Query: Trajectory of motion of an electron in the Coulomb scattering in terms
  of the Schroedinger wave equation and the Hamilton Jacobi equation   The trajectory of motion of a scattering electron in the Coulomb potential
from the wave function of the Schroedinger equation is presented in two ways,
spherical polar coordinates and Temple coordinates, and is compared with each
other and with the corresponding motion of classical mechanics. A good
correspondence among dynamics by wave functions and the classical dynamics has
been acknowledged by comparing computed examples.Detailed computing examples
discriminate the optimal dynamics of the wave function that should be verified
by an experiment.
