  Channeling properties and radiation spectra are studied on the grounds of
numerical simulations for the 855 MeV electrons in a periodically bent diamond
crystal. The bent crystalline profiles are shown to enhance the re-channeling
of the projectiles and to produce distinct lines in the radiation spectra. The
results obtained are analyzed and contrasted to the properties of the planar
channeling and of the channeling in uniformly bent crystals.
