Query: The effect of coordinate and momentum uncertainties on collision of
  coherent electrons   We have examined the head-on collision of two electrons in approximation of
coherent states. We have shown that the character of collision depends mainly
on ratio of initial relative electron's momentum to momentum uncertainty of
electrons. When this ratio becomes greater then 1, the Coulomb interaction does
not practically influence the scattering.
