The mechanism and kinetics of O3 formation after an electron pulse have been studied in the Ar-O2 systems by time resolved optical measurements at gamma = 260 nm. The second order rate constant of energy transfer from excited Ar(4s,4p) states to O2 molecules: (1) Ar*,Ar** + O2 → O2* + Ar, was found to be (8.9 ± 2.1) x 10-10 cm3 s-1. It was found also the evidence of the third order process contribution...
The mechanism and kinetics of energy transfer from highly excited Xe states (Eex > 9.5 eV), generated by a 12-ns electron beam, to chlorine donor molecules were deduced from time-resolved spectra of fluorescence in the region 240–340 nm. The emissions at 240–250 nm were assigned to Xe2** excimers, and those at 308 and 340 nm to XeCl(B) and XeCl(C) states. Kinetic analysis of the recorded spectra...
