  We analyze neutrino oscillations in a thought experiment in which neutrinos
are produced by electrons on target nuclei. The neutrinos are detected through
charged lepton production in their collision with nuclei in detector. Both the
target and the detector are assumed to be crystals. The neutrinos are described
by propagators. We find that different neutrino mass eigenstates have equal
energies.
  We reproduce the standard phase of oscillations and demonstrate that at large
distance from the production point oscillations disappear.
