Three Dimensional Analysis for Loss Prosesses of N_2(A^3Σ^+_u)
Abstract
Behavior of the loss processes of the metastable nitrogen molecules N_2(A^3Σ^+_u) in the cylindrical cavity is analyzed by the three dimensional diffusion equation by using the boundary condition of the third kind that can take account of the reflection at the electrode surface and the cylindrical side. Previously, we have carried out the same analysis in the one dimensional diffusion equation (S.Suzuki, H.Itoh, N.Ikuta and H.Sekizawa: J.Phys.D: Appl.Phys., 25, 1568 (1992).). The results of these theory were compared with the experimentals (S.Suzuki, H.Itoh, H.Sekizawa and N.Ikuta: J.Phys.Soc.Jpn., 62, 2692 (1993).) (S.Suzuki, H.Itoh, H.Sekizawa and N.Ikuta: Jpn.J.Appl.Phys., 36,Part 1, No.7B, 4744 (1997).), and the reasonable agreement was recognized in both results. By this analysis, we can discuss the diffusion of N_2(A^3Σ^+_u) from the radial direction to the axial direction in including the transition region for both directions. Furthermore, we report on the behavior of τ1 due to the each variation of the reflection coefficient at the electrode surface and the cylindrical side.
