Query: Tunneling of slow quantum packets through the high Coulomb barrier   We study the tunneling of slow quantum packets through a high Coulomb
barrier. We show that the transmission coefficient can be quite different from
the standard expression obtained in the plane wave (WKB) approximation (and
larger by many orders of magnitude), even if the momentum dispersion is much
smaller than the mean value of the momentum.
