EXPERIMENTAL STUDIES ON HEAVY ION EXCHANGE IN AIR.
Abstract
Charge-changing collisions between Al+ ions and the gases Ar, N2, O2, and air were examined over the velocity range 0.25 to 1.9 x 10 to 8th power cm/sec. Fast particle detection was used to obtain values for the electron capture cross section sigma-10, and the ion stripping cross sections sigma-12 and sigma-13. Higher ion stripping cross sections and capture cross sections to form negative ions of Al were negligible in comparison. In the lower velocity range (0.25 to 0.8 x 10 to the 8th power cm/sec), measurements of the total apparent ionization cross section of the target gas were made using slow particle detection. Estimates of the neutral Al stripping were made at the higher velocities, and these were found to be almost an order of magnitude higher then sigma-10. Ion sources for Al(+) and other metallic ions are discussed together with general considerations pertaining to experiments using such ions. (Author)
