Spatial quantum beats in vibrational resonant inelastic soft x-ray scattering at dissociating States in oxygen.

Summary, in English

Resonant inelastic soft x-ray scattering (RIXS) spectra excited at the 1σ_{g}→3σ_{u} resonance in gas-phase O_{2} show excitations due to the nuclear degrees of freedom with up to 35 well-resolved discrete vibronic states and a continuum due to the kinetic energy distribution of the separated atoms. The RIXS profile demonstrates spatial quantum beats caused by two interfering wave packets with different momenta as the atoms separate. Thomson scattering strongly affects both the spectral profile and the scattering anisotropy.
