Abstract:

The report presents the results of an investigation of Barium excitation by molecular beam magnetic resonance techniques. The results of both depopulation and ionization experiments are consistent and confirm that the metastable states in barium are strong contributors to photoionization in barium clouds under solar radiation. The depopulation experiments indicate that the major losses occur due to photons near 3005 A and that considerable metastable density increases occur when the atomic barium beam is subjected to a full light spectrum. The ionization experiments show that roughly half of the photo- ionization for equally populated metastables occurs from the singlets and half from the triplet metastable states. The report also presents a discussion of the mechanisms that decrease metal atom densities with emphasis on barium oxide, aluminum oxide and boron oxide reactions.
