Abstract Vibrationally resolved carbon 1s photoelectron spectra of methane are measured over a photon energy range between 300 and 480 eV. The intensity ratios of the vibrational components vary significantly, exhibiting a minimum at about 330 eV. The observed non-FC distribution is tentatively explained as a result of the internal inelastic scattering of the photoelectron on valence electrons, which leads to the loss of the photoelectron current that depends on the vibrational excitation of… CONTINUE READING
