 Title: TUNABLE LASER PHOTODETACHMENT OF SODIUM HALIDE NEGATIVE IONS Creators: Novick, Stewart E.; Mulloney, Thomas J.; Lineberger, W. Carl Issue Date: 1977 Publisher: Ohio State University Abstract: Ion beams of $NaCl^{-}, NaBr^{-}$, and $NaI^{-}$ are crossed with the photon beam of a tunable dye laser. The detached electrons and the resulting neutrals from the process $$NaX^{-} + h\nu = NaX + e^{-}$$ are monitored as a function of photon energy. The resulting photodet achment spectra show evidence for detachment via an excited state of the negative ion embedded in the detachment continuum. $$NaX^{-}(^{2}{\Sigma} ) + h\nu \rightarrow {NaX^{-}(^{2}\Pi)} \rightarrow NaX({^{1}}\Sigma) + e^{-}.$$ Description: Author Institution: Joint Institute for Laboratory Astrophysics, University of Colorado, Boulder 80309 and National Bureau of Standards URI: http://hdl.handle.net/1811/10105 Other Identifiers: 1977-RC-7
