Loss Processes of N₂(A³<i>Σ</i>⁺_u) in N₂+CO Mixture Gases

Abstract

Previously, we investigated the destruction processes of metastable nitrogen molecules N 2 (A 3 Σ 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 N 2 +CO mixture gases in order to investigate the influence of added CO on N 2 (A 3 Σ u + ). In the low pressure region, the experimentally obtained effective lifetime τ 1 of N 2 (A 3 Σ u + ) decreases only slightly with an increase in CO content. On the other hand, the reflection coefficient of N 2 (A 3 Σ u + ) on the electrode surface seems to become smaller by adding CO molecules, although scattering of the measured values are appreciable.
