Vibrationally state-selective electron-molecule collision processes involving CH(v) and the H2-(2Sg ) resonance

We report on the results of cross-section calculations for the following three types of electron impact processes: 1) vibrational state-selective excitation of CH(X; v) to its first three ectronically excited states CH(A; v’), CH(B; v’) and CH(C; v’), 2) resonant vibrational excitation of H2 (v ) via its H2−(2Sg+) resonance at 14 eV and 3) dissociative electron attachment on H2(v) via the same esonance producing H− and H(n = 2). All these processes play an important role in the divertor plasmas of magnetic fusion devices.
