Project LABSTAR: Study of the Formation and Structure of Excited High-Temperature Metal Compounds.
Abstract
The chemiluminescent reactions of metal atoms with various oxidizer gases had been investigated under single-collision conditions using a beam-plus-gas experimental arrangement. From these studies we have established new ground state dissociation energy for CAO, SRO, BAO, PBO, EUO, EUF, SMO and SMF. Much of the interest assoicated with these reactions is the possibility of constructing a chemically-driven short-wavelength laser. For this purpose we have made lifetime measurements of various excited states and determined the probability of producing an excited molecule for each molecule of reactant consumed. We find for all the systems we have investigated that the initial yield of excited-state products is very low, on the order of 1% or less. This suggests that secondary collisions of vibrationally 'hot' products may play an important role in causing the high excited-state yields observed in the torr pressure regime. (Author)
