Mass Spectrometry of Laser Generated Negative InP Cluster Ions
Abstract:
Both positive and negative InP cluster ions were generated on a self-built laser probe time-of-flight mass spectrometer. The negative mass spectra showed an alternation of the cluster ion intensities with the odd/even total number of atoms in the clusters. This result is attributed to that all the valence electrons in the clusters of odd atom number are paired, thus stable. It is proposed that, based on the above result, the stability of such cluster ions depends more on their electronic structures than on their geometric structures. Further studies on both theoritical computation and experimentation are being carried on.
