The threshold for single photon ionization was measured by using a pulsed frequency doubled visible dye laser or a UV dye laser and detecting ions with a quadrupole mass spectrometer. Resonant two photon ionization and depletion spectroscopy were employed to record optical spectra. Unfortunately, the exothermic reaction yields rather warm clusters and no vibrational structure was resolved. While our measured photoionization threshold $I_{p} = 3.81 (5) eV$ for $Na_{2}F$ is in good agreement with former $experiments^{1}$ we determined $I_{p} = 3.57 (5) eV$ for $Na_{3}O$ which is significantly lower than the previously published value of $3.90 (15) eV.^{2}$ en_US dc.format.extent 61538 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title PHOTOIONIZATION AND OPTICAL ABSORPTION OF $Na_{2}F$ AND $Na_{3}O$, en_US dc.type article en_US
