Doppler Shift in Electron Waves

[uunet!mailrus!samsung!ulowe...@ncar.ucar.edu]

Does anyone know if there has been research on the possible Doppler shift of
electron waves? Any ideas about how we can put this Doppler shift to good use?

This "Doppler shift" is put to good use every day in particle accelerators
at SLAC, Fermilab, CERN, ... For electrons, the Doppler shift (describing the
change of frequency of a wave emitted by a moving source) is describing
PRECISELY the same effect as the statement that the energy of a moving electron
is related to its momentum by the fundamental relation of special relativity,
E = sqrt (p^2 + m^2) (in units where c=1). This relation is "used"
(or "tested") by the operation of every syncrotron particle accelerator.
