INTERACTIONS OF SLOW H, H-2, AND H-3 WITH THIN CARBON FOILS

Interaction processes resulting from the transit of incident 2-30 keV H+, H-2+ and H-3+ through 1.2 to 2.5 mug cm-2 carbon foils are investigated by examining the charge state and angular scatter distributions Of atomic and molecular species that exit the foils. A comparison of the scatter distributions of exiting H-2+ and H-0 from incident H-2+ and H-3+ show that the atomic components of transmitted molecules scatter independently from foil atoms. For a given foil thickness, the measured fractions of H-2+ from incident H-2+ and H-3+ are inversely proportional to the square of the angular scatter half-width.
