COMMENTS: Shock heating of ethylene/argon mixtures

A microwave N2 discharge lamp was used to generate light of 174 nm

The measured data points for the effective extinction coefficient α(T) in cm2/mol (base e) plotted in Fig. 4 have been digitized and converted to absorption cross sections (conversion factor 1.66×10-24)
