Abstract

Vibrationally resolved O 1s photoelectron angular distributions from CO2 molecules, aligned parallel and perpendicular to the electric vector of the incident light, have been measured in the 5σg* shape resonance region, with photon energies up to 2 eV above the O 1s ionization threshold, using multiple-coincidence electron-ion momentum imaging spectroscopy. The angular distributions depend on the vibrational quanta of the antisymmetric vibrations in the O 1s ionized state but do not vary significantly as a function of the photon energy across the 5σg* shape resonance.
