Obviously, the clusters NaAry (c), NaAry (c), NaAr4 (c), NaAry (d), and NaAre (c), which correspond to the simple van der Waals long distance addition of a excited sodium atom to an argon cluster, are characterized by 3p states and 3s states only weakly shifted with respect to the isolated atom limit. Their emission lines are therefore very close to the atomic line.

Since his arrival at McMaster in 1988, Randall Dumont has focused on statistical theories and their origin in quantum and classical mechanics. His interests include the development of Monte Carlo implementations of statistical theory wherein dynamical processes are simulated by random walks on potential energy surfaces. The breakdown of statistical theory and the appearance of nonexponential population decay are also topics of his ongoing investigations. Other questions of interest are the incorporation of quantum effects into statistical theory and the effects of collisions on reaction processes. He has a special interest in argon cluster evaporation in vacuum197 and in the description of simple isomerization reactions.198 His other interests include the semiclassical description of classically unallowed processes such as tunneling.199... 

It has been shown, by electron impact ionization, that the double ionization thresholds of stable doubly charged argon cluster ions are considerably lowered (32.0 eV) (Scheier and Mark 1987a) compared with the atomic dication (43.4 eV) (Holland et al. 1979). 

Dehmer and Pratt were one of the earliest groups to observe resonance structures in the photoionization efficiency (PIE) curves of small argon ions and mixed rare gas cluster ions (Dehmer and Pratt 1982 Pratt and Dehmer 1982). The structures in the PIE curves of small argon cluster ions were attributed to interband transitions while the features observed in the PIE curves of mixed rare gas cluster ions were suggested to arise from autoionizing states. Walters et al. (1985) also observed similar resonances in the PIE curves of C6H6/HC1... 

Recently, Foltin et al. (199 la,b) have reported an unusual metastable decomposition channel in singly charged argon cluster ions involving the loss of a number of argon atoms. The number of argon atoms lost increases from two for Ar to ten...
