We present a direct measurement of the velocity dependence of the associative-ionization (AI) cross section for collisions between Na ( 3 P) atoms in the energy range 0.08 – 0.29 eV in a crossed-beam experiment using a Doppler-shift velocity-selection technique. The AI cross section at first decreases, reaches a minimum at about 0.15 eV, then sharply increases with collision energy. Interpretation of the results in terms of a semiclassical theory of AI indicates that more than one potential surface of Na ( 2 P + 2 P) must be involved in the AI process.
