    Energy and angular distributions in dissociative photodetachment of O−4 (1995)

    Notes: An anisotropic product angular distribution has been observed in the dissociative photodetachment of O−4 at 523 nm. Energy and angular distributions of coincident O2 products from the process O−4+hν→O2+O2+e− were measured using translational energy spectroscopy in a fast ion beam. The angular distribution peaks perpendicular to the electric vector of the laser beam. © 1995 American Institute of Physics.

    Translational spectroscopy studies of the photodissociation dynamics of O−4 (1996)

    Notes: An investigation of the photodissociation dynamics of the dimer anion O−4 at 523.6, 349.0, and 261.8 nm is reported. Product translational energy and angular distributions have been obtained using photofragment translational spectroscopy in a fast ion beam. At all wavelengths photodissociation (O−4+hν→O2+O−2) is observed to proceed via a rapid parallel electronic transition, with the photofragment angular distribution strongly peaked along the laser electric vector. The lowest energy photodissociation channel produces O2(a1Δg) and ground state O−2(X2Πg), indicating that O−4 is a doublet anion. The partitioning of energy in the dissociation reveals a complicated wavelength dependence. © 1996 American Institute of Physics.

    Fast-ion-beam photoelectron spectrometer (1995)
    [S.l.] : American Institute of Physics (AIP)

    Notes: A high-collection-efficiency fast-ion-beam photoelectron spectrometer is described. In a straight time-of-flight mode, the spectrometer collects ∼1% of the photoelectrons and achieves an energy resolution of ΔE/E of ∼5%. For coincidence experiments requiring greater collection efficiency, a paraboloidal electrostatic mirror is used. The mirror collects ∼40% of the photoelectrons while maintaining ΔE/E≤35%. In both modes of operation, a time- and position-sensitive electron detector allows conversion of the photoelectron laboratory energy to center-of-mass energy. The fast-ion-beam photoelectron spectrometer is used to prepare mass- and energy-selected neutral molecules which are used in molecular dissociation studies. © 1995 American Institute of Physics.
