Abstract

Crossed-beam chemical reactions of excimer laser-generated metal atoms (Al, Ba, La, Ce, Gd, and Dy) with oxidants are studied under the condition of high collisional energy. Electronically excited metal monoxides are positively identified by their chemiluminescent spectra. From time- and spectrally-resolved emission studies, the dominant role of high-speed, ground state metal atoms in these chemiluminescent reactions is revealed. State-resolved excitation functions at high collisional energy are obtained for Ba + O₂ reaction. To the exclusion of Al + O₂ reaction, all the systems display anisotropic angular distributions of chemiluminescence. A Newton diagram analysis of the observed chemiluminescent spatial patterns infers direct reactions with backward scatterings for these metal atom + O₂ reactions at high collisional energy.
