Quantum efficiency of the formation of KrF* as a resuit of radiative collisions in a Kr–F2 mixture

Radiative collisions in a Kr–F₂ mixture were recorded in the range 118 nm < λ < 121.6 nm. At the wavelength L_a (121.6 nm) the reduced absorption coefficient was q = (1.33 ± 0.06) X 10^{– 38} cm⁵. The quantum efficiency of the formation of KrF* was within the range 0.85–1.0. The measured rate constant of quenching of the KrF* molecule by molecular fluorine was K_F2 = (4.5 ± 0.5) X 10^{– 10} cm³/s.
