Abstract:
Results are presented of an investigation of the heterogeneous photochemical reaction between Ge and Br2, the Br2 molecule being excited by λ = 514.5 nm high-poiwer argon laser radiation in the predissociation range. The dependence of the reaction rate on the irradiation intensity has a well-defined nonlinear character. The explanation of this effect is found by analyzing the chemcal kinetics of this reaction. The possibility of utilizing the heterogeneous photochemical reaction between Ge and Br2 for laser separation of bromine isotopes is discussed.
