Abstract: | Interaction processes resulting from the transit of incident 2–30 keV H+, H+2 and H+3 through 1.2 to 2.5 μg 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 H0 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. |
