Abstract

Collisions of metastable Mg*(³P) and Ca*(³P, ¹D) atoms with CF₄, CCl₄, and CBr₄ were studied in a beam-gas arrangement. The total attenuation cross sections determined for the reactive systems vary in a wide range increasing with electron affinity of the target gas. The reactions of metastable Mg*(³P) with CX₄ yield no chemiluminescence. All Ca* + CX₄ reactions give electronically excited CaX* products and the chemiluminescence yield increases with reaction exo-ergicity.
