We have determined absolute apparent excitation cross sections for photoemission in the 300–1050 nm spectral region resulting from collisions of I 2 with electrons of 4.8–100 eV translational energy. Experiments were done in single collision conditions and emission is observed from I 2 , I 2 + , I and I + . All the emission features appear to turn on at the energy thresholds for formation of the respective excited state species. At higher electron beam energy the spectra are dominated by emissions from the strong I 2 + A–X band, as well as the intense emission from several I 5 s 2 5 p 4 6 s states. An attempt to determine the initial I 2 + A populations generated from electron impact is discussed. These populations are determined from simulations of the I 2 + A–X emission band using both experimentally and theoretically determined p...

I 2与5-100 eV电子碰撞产生的光发射

我们已经确定了I 2与4.8-100 eV平移能电子的碰撞导致的300-1050 nm光谱区域内光发射的绝对表观激发截面。在单个碰撞条件下进行了实验，从I 2，I 2 +，I和I +观察到了发射。所有的发射特征似乎在形成各自的激发态物质的能量阈值处开启。在较高的电子束能量下，光谱主要由强I 2 + A–X波段的发射以及几种I 5 s 2 5 p 4 6 s态的强发射所主导。讨论了确定由电子撞击产生的初始I 2 + A种群的尝试。这些种群是根据I 2 + A–X发射带的模拟，使用实验和理论上确定的p来确定的。
