抜粋

Observations of Auger transitions to quasi-stable states of CO2+ subsequent to C 1s-1 and O 1s-1 ionizations of CO are presented along with the corresponding photoelectron spectra and calculations of the potential energy curves. The equilibrium distances Re, the vibrational energies ℏω, and the anharmoncities xℏω, for the final states a1Σ+, b1Π, A3Σ+, and d1Σ+ are derived from fits to the spectra by assuming Morse potentials. A comparison of these Morse potentials with theoretical potential energy curves reveals excellent agreement in the Franck-Condon regions of the Auger transitions. The relative intensities for the observed C 1s-1 and O 1s-1 Auger transitions are also derived.
