Optical Electron Excitation Cross-Section Measurements of the N2(+) First Negative System at Elevated Temperatures
Abstract
Optical electron excitation cross sections of bands of the -2 and -3 sequences of the N2(+) First Negative System of N2 were measured over the temperature range from 300 to 900K. The apparent electron excitation cross sections of the v = 1, 2, 3, and 4 levels, normalized to the v = 0 level, were determined, and enhancement of the experimental values of sigma(v> or = 2) relative to the predicted values was found for all temperatures investigated. Possible causes of the enhancement and its decrease with increasing temperature are discussed.
