McLaughlin Title: On the dissociation of nitrogen by electron impact and by E.U.V. photo-absorption Journal/Source: Planetary and Space Science, 26 (5), 449-462, (1978); http://dx.doi.org/10.1016/0032-0633(78)90066-1 Data: diagram Energy/Wavelength range: 11 - 24 eV (~ 52 - 112 nm) Resolution: Temperature: Temperature dependence: Pressure/Concentration: Phase: gas pH Comments: The dissociation of N2 by electron impact and by e.u.v. photo-absorption is studied, and it is shown that the forbidden predissociation of the numerous valence and Rydberg states of N2 in the 11-24eV energy range is the dominant mechanism for N atom production. The total cross section for exciting N2 e.u.v. radiation in the 800Å-1100Å wavelength range has been measured and found to have a value of 3.4 x10-17 cm2 at 100 eV under optically thin conditions.
