Resonance in Collision Processes

Abstract

The limitations are investigated under which "resonance" provides certain collision processes with preferred probability. In impacts of the second kind, resonance strongly affects the transfer of electronic into electronic energy or into a small amount of vibrational energy, possibly the transfer of vibration into vibration, certainly not the transfer of vibration into rotation. Resonance is not effective in the transfer of energy of atomic recombination into electronic energy and, in general, resonance is not effective in processes in which nuclei change positions by appreciable amounts.
