Angular Momentum Distributions of Autoionizing States Produced by 1.5-5-MeVC+Ions in Carbon Foils

Abstract
Orbital angular momentum (l) distributions of ions in intermediate n and l states have been compared for 1.5-5-MeV carbon ions traversing C foils and He gases by projectile Auger spectroscopy. The degree of high-l enhancement in C targets is quantitatively established. A picture involving multiple collisions between target atoms and the entrained electrons which accompany the ions explains the results.
