We calculate the bremsstrahlung emitted by heavy bare ions penetrating single crystals at highly relativistic energies. The main component, originating in scattering of the virtual photons of screened target nuclei on the projectile, appears with energies of, approximately, 25γ MeV for a lead ion (γ ≡ E/Mc2 where E and M denote projectile energy and mass). It shows dips in yield upon variation of the incidence angle to major crystallographic directions quite similar to those of other close-encounter processes. Incoherent interaction with single target electrons gives rise to two additional but quite different bremsstrahlung components, a moderate component distributed over the same frequencies as the main component, and a strong component confined to low energies. The channeling characteristics of the total bremsstrahlung spectrum vary substantially with photon energy.
