Description

O K-shell photoionization of the CO2 molecule causes antisymmetric vibrations v3' in the core-ionized molecule. The v3'-resolved partial cross sections σ+v3' and asymmetry parameters βv3' are measured in the Σu shape resonance region above the O K-shell ionization threshold of the CO2 molecule. Neither the shape resonance energy in σ+v3' nor the value of βv3' shows v3'-dependence. This v3'-independent nature is attributed to the fact that v3' vibrations do not cause any change of the size of the potential box responsible for the formation of the shape resonance. Multiple scattering calculations employing the v3'-dependent fixed-nuclei approximation reproduce well the measured v3'-resolved partial cross sections
