The visible and near-UV emission spectroscopy of methane (CH4) induced by a femtosecond intense laser field (800 nm, 40 fs, 1014 W/cm2) is studied. By measuring the decay profiles of the neutral fragment product CH (A2Δ → X2Π), two reaction pathways, i.e., the electron-ion recombination through e^{-
