Abstract
The total absorption, photoionization, and dissociativephotoionization cross sections of ammonia have been measured from 80 to 1120 Å. All possible fragment ions have been observed including doubly ionized ammonia. The absolute ionization efficiencies have also been measured in this spectral range. The appearance potentials of the fragment ions have been measured and are compared with the calculated appearance potentials derived from published heats of formation and ionization potentials of the fragments.Keywords
