CS2分子Penning电离的流动余辉光谱测量
Spectra of ionized CS2in Penning ionization flowing afterglow
摘要
用PIOS(Penning Ionization Opnieal Spectroseopy)方法首次观察到470～490nm间CS+(A-X)13-2、14-3的发射带,发现此发射带偏重于在Ne/CS2中产生.这些谱带的产生可用二次碰撞模型加以解释.
Abstract
PIOS (penning ionization optical spectroscopy) method was used to investigate structure of ionized CS2. Emission of CS+ (A2∏i→X2∑+) 13-2 and 14-3 bands in CS2/He and OS2/Ne penning ionization flowing afterglow was observed in the wavelength region between 470-490nm when high discharge current was used. Experimental result showed that the above emission was preferential in CS2/Ne system. Secondary collision was assumed as the reason of the emerging of these emisson.
