LOSS PROCESSES OF N2(A3-SIGMA-MU+) IN N2+CO MIXTURE GASES

Previously, we investigated the destruction processes of metastable nitrogen molecules N2(A3 SIGMA(u)+), and analyzed the experimental data by taking the reflection of metastables at the boundary into account. In this paper, the work is extended to N2 + CO mixture gases in order to investigate the influence of added CO on N2(A3 SIGMA(u)+). In the low pressure region, the experimentally obtained effective lifetime tau1 of N2(A3 SIGMA(u)+) decreases only slightly with an increase in CO content. On the other hand, the reflection coefficient of N2(A3 SIGMA(u)+) on the electrode surface seems to become smaller by adding CO molecules, although scattering of the measured values are appreciable.
