According to recent research from Yerevan, Armenia, "In the present
paper, we investigate coherent bremsstrahlung of high energy electrons
moving in a periodically deformed single crystal with a complex
base. The formula for corresponding differential cross-section is
derived for an arbitrary deformation field."

"The conditions are discussed under which the influence of the
deformation is important. The case is considered in detail when the
electron enters into the crystal at small angles with respect to a
crystallographic axis," wrote A.R. Lazarian and colleagues.

The researchers concluded: "It is shown that independence of the
parameters, the presence of the deformation can either enhance or
reduce the bremsstrahlung cross-section."

Lazarian and colleagues published their study in Modern
Physics Letters B (COHERENT BREMSSTRAHLUNG IN PERIODICALLY
DEFORMED CRYSTALS WITH A COMPLEX BASE. Modern Physics Letters B,
2009;23(20-21):2573-2584).
