Gigantic Shift of X-Ray Beam in Deformed Crystals

摘要: We develop a theory for the trajectory of an x ray in presence crystal deformation. A set equations motion x-ray wave packet including dynamical diffraction is derived, taking into account Berry phase as correction to geometrical optics. The has shift center position due Remarkably, vicinity Bragg condition, enhanced by factor $\omega /\Delta \omega$ ($\omega$: frequency ray, $\Delta\omega$: gap induced reflection). Comparison with conventional also made.
