Photoionization Mass Spectrometric Study of Neutral Bare Aluminum Clusters and Aluminum-Carbon Mixed Clusters

摘要

Photoionization time of flight mass spectra of bare aluminum and aluminum-carbon mixed clusters as well as a variety of oxygen-and oxygen-carbon-adducted aluminum clusters are recorded and assigned.The discontinuities in the mass abundance spectra at AI_(7),AI_(13),AI_(23),AI_(7)C,AI_(13)C,and AI_(24)C are revealed.The findings are interpreted in terms of the electronic and geometric structures of these species.
