摘要：

Hydrogenic ions penetrating a crystal are perturbed by the frequency with which they pass atoms lying in rows or ordered planes. This frequency, when resonant, can cause excitation of the ion with subsequent collisional ionization or radiative relaxation following escape from the crystal. The various possible m states being non-degenerate in the channel are separable. The associated alignment is observed in both the separate ionization probabilities and X-ray anisotropy.
