Energy transfers in Ar-Xe and Ne-Xe mixtures excited by alpha particles. II. Kinetic study

For pt.I see ibid., vol.25, no.23, p.5141-8 (1992). In Ne-Xe mixtures molecular states responsible for the second continuum of xenon ( lambda =170 nm) are shown to be created by homonuclear and heteronuclear reactions from the 3 P 1 and 3 P 2 states of xenon. In Ar-Xe mixtures, at lambda =826 nm, two lines of argon and xenon are superimposed; it is observed that the atomic states responsible for the two transitions undergo decay (for argon) or creation (for xenon). The creation of the 2p 10 xenon state is measured from the transition at lambda =980 nm which it produces. In the Ne-Xe mixture, at lambda =882 nm, it is the decay, through homonuclear and heteronuclear mechanisms, of the precursor 2p 8 state of xenon which is demonstrated. In each case, the rate constants of the corresponding reactions are reported.
