Electron Attachment and Molecular Fragmentation in Laser-Excited Plasmas
Abstract
Production of O- from thermal electrons has been identified during the laser excitation of NO. O- is produced during excitation near 226 nm, corresponding to absorption in the (0,0) band of the A-X band system of NO. Electrons with energy limited to <0.5 eV completely suppress the endothermic production of O- from NO(X2II). Dissociative attachment occurs from the A2 + electronic state of NO and produces both O- and N in their ground electronic states. This is the first reported case of dissociative attachment of electrons to an optically prepared excited electronic state. Keywords: Multiphoton ionization; Capture; Attachment; Detection; Ion; Nitric oxide.
