Abstract : Charge-changing collisions between K, Rb, Cs, Sb, Sr, I, Be, and Xe ions and the gases Ar, N2, and O2 were measured in the low energy range (4 to 130 keV). Similar measurements were made for K and Sr in the intermediate and high energy range (0.1 to 2 MeV) as well as rechecks on the previous measurements for Al in the intermediate and high energy ranges. High energy (0.2 to 2 MeV) measurements were made with Ag and Sb. Fast-particle detection was used to obtain values for the electron capture cross sections sigma 10 and sigma 21, the ion-stripping cross sections sigma 12, sigma 13, sigma 14, and sigma 15, and the neutral-atom-stripping cross section sigma 01. An oven was developed to provide a collision region containing oxygen mainly in the ground atomic state, but time permitted only preliminary tests without oxygen. (Author)
