Abstract Loss of the metastable nitrogen molecule N 2 (A 3 Σ + u ) in plane parallel electrodes has been investigated by us previously by solving the diffusion equation. Our procedure is based on an analysis using the third kind of boundary condition, which can take account of finite values for the density of N 2 (A 3 Σ + u ) at the electrode surfaces. The values of the effective lifetime of N 2 (A 3 Σ + u ) calculated from this analysis were reasonably consistent with our experiments. This paper describes the behavior of the effective lifetimes of RN 2 (A 3 Σ + u ) in a cylindrical cavity. The analytical treatment of the diffusion equation for N 2 (A 3 Σ + u ) proposed by us is extended to three‐dimensional space. We systematically report the effective lifetimes of metastable molecules in a cylindrical cavity. © 2000 Scripta Technica, Electr Eng Jpn, 130(4): 1–8, 2000
