N2 - We have measured and report the total gas-number-density normalized effective ionization coefficient, ᾱ/N, as a function of the density-reduced electric field, E/N for Ar, CO2, CF4, the binary gas mixtures CF4:Ar (20:80), CO2:Ar(20:80), CO 2:CH4(20:80) and for the ternary gas mixtures CO 2:CF4:Ar (10:10:80) and H2O:CF 4:Ar(2:18:80). We also report the limiting value, (E/N)lim of the above gaseous systems. A comparison of our results on the unitary gases shows good agreement with previous measurements. The results on the ternary mixtures show that the addition of CO2 or H2O to the binary gas mixture CF4:Ar lowers the electron energies and increases ᾱ/N(E/N).
