Abstract

The negative ion PtN- has been studied by autodetachment spectroscopy in a coaxial laser-ion beam spectrometer. Sharp resonances were observed at photon energies near the photodetachment threshold, and the sharp structure could be assigned as 11(v=0) transition, followed by autodetachment of the 1 state. A rotational assignment was accomplished and the observed linewidths as a function of rotational energy elucidate the dynamics of the autodetachment process. Saturation of this transition and the resulting optical pumping dips give a unique method of determining the absolute cross section of the transition. © 1987 The American Physical Society.
