Resonant inelastic x-ray scattering (RIXS) is a major method for investigation of electronic structure and dynamics, with applications ranging from basic atomic physics to materials science. In RIXS applied inversion-symmetric systems, it has generally been accepted that strict parity selectivity applies in the sub–kilo–electron volt region. contrast, we show selection rule violated spectra free homonuclear diatomic O 2 molecule. By analyzing spectral dependence on angle, demonstrate...
We study the rotational dynamics induced by recoil effect in diatomic molecules using time-resolved two-color x-ray pump-probe spectroscopy. A short pump pulse ionizes a valence electron inducing molecular wave packet, whereas second time-delayed probes dynamics. An accurate theoretical description is used for analytical discussions and numerical simulations. Our main attention paid to following two interference effects that influence recoil-induced dynamics: (i) Cohen-Fano (CF) two-center...
