Charge-changing collisions between Al, Fe, and U, and the gases Ar, N2, O2, and air have been examined over the velocity range 0.25 to 3.7 x 10 to the minus 8th power cmsec. Fast particle detection was used to obtain values for the electron-capture cross section sigma sub 10, the ion-stripping cross sections sigma sub 12, sigma sub 13, and sigma sub 14, and the neutral atom-stripping cross section sigma sub 01.-sigma sub 01 for K, Te, and Ag. These sigma sub 01 cross sections are roughly the same for all metal atoms with the exception of U, which was larger. Sigma sub 10 is in all cases almost an order of magnitude smaller than sigma sub 01. Sources for the production of metallic ions are discussed together with general considerations pertaining to experiments using such ions. Author
