Charge states of slow (v{approx}0.3v{sub Bohr}) highly charged ions (O{sup 7+}, Ar{sup 16,18+}, Kr{sup 33+}, Th{sup 65+}) have been determined after transmission through 10nm thick amorphous carbon foils. Up to the highest charge states, ions reach charge state equilibrium in the foils within less than 21fs. High yields of secondary ions are emitted from the foils as a result of the dissipation of tens to hundreds of keV of potential energy during ion neutralization. Positive secondary carbon… Expand
