Fragment ion-photon coincidence (FIPCO) spectra by controlled electron impact on methane have been observed. To identify the observed ions correlating with photons and to estimate their translational energy distributions, Monte Carlo calculations have been carried out. These results indicated that the CH+ ion correlates with its own A-X and 3 ∑-3∏ emissions in the FIPCO spectra. The translational energy of CH+(A) was 0.20eV, whereas that Of CH+(3∑)Was described by a Boltzmann distribution of 1000 K.
