摘要

We obtain rate coefficients for mixtures of O-2 and N-2 as well as pure O-2, by fitting pulsed Townsend measurements over a large pressure range from 3 kPa to 100 kPa in a density-reduced electric field range from 40 to 110 Td (1 Td = 10(-21) Vm(2)). The applied model includes ionization, dissociative attachment to O- and non-dissociative attachment to O-2(-), O- and O-2(-) detachment, as well as charge transfer and ion conversion from O- to O-2(-) and O-3(-). The results are compared to Bolsig+ and MAGBOLTZ simulations and experimental data, where available. The key novelty is the simultaneously obtained rate coefficients from a single pulsed Townsend experiment including several ion processes over the whole N-2-O-2 mixing range.
