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 with electron beam ionization, 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.
