Results are presented of an investigation of the heterogeneous photochemical reaction between Ge and Br 2 , the Br 2 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 Br 2 for laser separation of bromine isotopes is discussed.
