Abstract

Chemiluminescent reactions of Ca*(³P_J) atoms with C₆H₅X (X = F, Cl, Br, I) and C₆F₅I molecules were studied in a beam-gas arrangement. The A –X ² and B ²–X ² transitions in calcium monohalide products have been observed for all targets except C₆H₅F. The total collision cross sections for the systems studied are about 10^-18 m², in agreement with the harpoon model, while the chemiluminescence photon yields are below 1%.
