Question

2-16. Distribution of Electron Energy Between Different Channels of Excitation and Ionization. After analyzing Figs. 2-27-2-34, identify molecular gasses with the highest ability to selectively localize discharge energy into vibrational excitation. What is the highest percentage of electron energy that can be selectively transferred to vibrational excitation? Which values of reduced electric field or electron temperatures are optimal to reach this selective regime? n. 100% Kr exctatn Arexcitaton ionzation s 10 Figure 2-27.
