Abstract
Dipole oscillator strengths for absorption parent-ion formation and fragmention formation of NH3 have been obtained, using techniques of energy-loss electron spectroscopy and electron-ion coincidence. The data have been analysed using branching ratios for the three electronic states of NH3+ which have been derived from a recent electron-electron coincidence experiment. The given fragmentation patterns for the three ionic states were found to give a reasonable fit to the data. Discrete excited states converging on both the 1e and 2a1 ionic limits were found to give rise to some neutral formation.Keywords
