Abstract
    We could resolve the spin-orbit splitting of 160+/-4 cm(-1) in the (2) Pi ground
    stale of O-2(-) anions by high resolution photodetachment photoelectron
    spectroscopy. The observed splitting is in good agreement with the
    theoretically derived value. Our directly measured electron affinity of O-2 is
    450 +/- 2 meV and deviates within experiment errors from previous values.
    kHz repetition rate was applied to avoid space charge and improve electron
    energy resolution in a time-of-flight electron energy analyzer. [References:
