| 摘 要： | 建立了一套交流放电产生离子分子束源的装置，以N2为例，束流中N＋2的发射谱强度远大于N2的发射谱强度，N+2(B)/N2(C)高达6∶1。根据其发射谱，对交流放电过程和浓度调制光谱进行了测量研究，并计算了离子分子激发态振动温度和转动温度，分别为3 310和282 K。

| Abstract: | An experimental apparatus using an AC discharge was developed for producing molecular ion beam. The emission spectral intensity of N2+ is stronger than that of N2, and a very high ratio of N2+ (B)/N2 (C) up to 6:1, was achieved in N2 discharge. The effects and processes of N2 discharge, and the concentration modulation spectra were studied. The vibrational temperature and rotational temperature of N2+ molecular ions beam were calculated to be 3 310 and 282 K respectively from the emission spectra. |
