Abstract:

This work contributed toward the development of aluminum cluster-containing materials for propulsion applications. To accomplish this, we conducted numerous experiments in the gas phase on aluminum-containing cluster anions, using negative ion photoelectron spectroscopy asour primary experimental tool. Along with mass spectrometry to identify and isolate massselect the cluster anions of interest, we also developed several novel ion sources. Once formed, we often directed the cluster anions of interest through an ion-neutral reactivity cell to generate reaction products, which were then subjected to anion photoelectron spectroscopic studies in order to characterize their electronic structures. Both the spectroscopic and the reactivity studies were closely supported by complementary calculations.
