title: Does Crystal Tilt Enhance the Electron Interaction?
abstract: : We have observed that a slight crystal tilt away from the zone axis paradoxically decreases the dynamical extinction length, as if the electron-crystal interaction increases. This effect disappears at larger tilt angles. Using the simplified channeling theory, this behavior is explained.
