Abstract

RECENT development of radiation chemistry, gaseous electronics, plasma physics, and reaction kinetics in flames requires full understanding of elementary reactions occurring in highly energized systems. A substantial class of these reactions represent those between excited neutral particles and atoms or molecules (collisions of the second kind). However, knowledge of these processes is so far very limited, even though their important role, for example, in ionization phenomena in gaseous mixtures (Penning effect) has been known for a long time1. The need for further investigation became particularly apparent when collisions of the second kind were found, in which unexpected ions like NeAr+, ArN2+, ArI+, CH4Xe+, C2H2Hg+ or N2Hg+ are formed2–6.
