利用能量损失电子能谱和电子-离子符合技术，获得了吸收母离子形成和 NH3 碎片形成的偶极子振荡器强度。使用 NH3+ 三种电子态的支化比对数据进行了分析，这些支化比源自最近的电子-电子符合实验。发现三种离子态的给定碎片模式与数据合理吻合。发现在 1e 和 2a1 离子极限上收敛的离散激发态会产生一些中性形成。
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.
