Abstract
The results of an experiment measuring the charge states of 1.5-, 3.0-, 6.0-, and 12.0- MeV iodine ions scattered through angles between 2.5° and 8.0° by single collisions with xenon atoms are reported. The charge states measured range from 9 to 27, and the charge-state distributions showed average values from 11 to 23. The variation of these average values with the collision's distance of closest approach shows the influence of the M and L shells of the colliding ions.
