  Identity of electrons leads to description of their states by symmetrical or
anti-symmetrical combination of free coherent states.
  Due to the coordinate uncertainty potential energy of the Coulomb repulsing
is limited from above and so when energy of electrons is large enough,
electrons go through each other, without noticing one another.
  We show existence of set of coherent states for which wave packages recession
vanish - electrons remain close regardless of Coulomb repulsion.
