Paper Abstract

Kinetics of Xe excitation in active nitrogen was stndied using XeCl* formation in reaction Xe* +Cl2(CCl4) as a monitor of Xe{6s} states. It was found out that Xe excitation involves energy transfer from N2* molecules formed in three body recombination. (M) N(4S) + N(4S) + Xe > N2(X,V) + Xe*({6s},{6s,},{6p})Excitation of Xe{6s} states shows termolecular kinetics with rate constants for M = He, Ar and Xe carriers respectively: 0.41 10-33, 0.86 10-33 and 1.10-33 in cm6/s, at room temperature. Thus the studied system manifests itself as having high quantum yield for conversion of chemical energy, released in the act of recombination into energy of excited Xe atoms or excimers.
