摘要：

Equilibrium and nonequilibrium charge-state distributions have been obtained for high-energy ions emerging from crystals. In a major channeling direction in silicon, the slower ions and those incident in low charge states emerge nearly at equilibrium, with a mean charge close to that in a random direction. High-energy channeled oxygen 8+ ions emerge far from equilibrium, indicating a capture cross section of less than 2× 10-19 cm2. © 1969 The American Physical Society.
