Pulsed Ge(n)(+) microcluster concentration spectra.

Bloomfield, Geusic, Freeman and Brown have used the Smalley synchronized laser and supersonic quenching carrier gas pulsed method to obtain spectra for Ge(n)(+) similar to pulsed spectra obtained previously for Si(n)(+). Their data are presented, compared to data obtained by a continuous method, and discussed extensively in order to separate effects due to cluster stabilization energies, growth kinetics and ionization fragmentation. Differences in chemical bonding and growth kinetics between Si(n)(+) and Ge(n)(+) microclusters are discussed.
