Scattered projectile angular distributions characteristic of surface channeling are observed. For both incident species, the dominant scattered charge fraction is neutral, which varies only by a few percent as a function of incident charge state. Significant O- formation is observed, which manifests a distinct velocity threshold. For incident Ar projectiles with open L-shell, the positive scattered charge fractions, while always less than about 10%, increase linearly with increasing number of initial L-shell vacancies. |
