Abstract

Collisional ionization of Cs and K atoms by O₂ has been studied in a crossed beam geometry from threshold to ∼100 eV alkali laboratory system energy. The energy spectra of forward directed positive (Cs⁺ and K⁺) and negative (O^- and O^-₂) ions were measured by electrostatic energy analysis. The dominant O ₂^- negative ion is associated with forward scattering of the alkali positive ion in the center-of-mass system but O^- production appears associated with backward scattering of the alkali ion.
