ABSTRACT
We report the first observation of energy losses and fractional neutralization of slow multicharged ions incident on a metal surface. Data were obtained on 374 eV per charge aluminum 3 ≤ z ≤ 6 ions incident on an uncharacterized gold surface at a grazing angle of 7° and scattered through 14°. The resulting atoms consisted of about 60% neutral and 40% singly charged ions in the case of incident z = 4 ions. The scattering process did not appreciably broaden the ion linewidths. The apparatus makes use of a laser generated heavy ion source.
