theoretically
using the stimulated X-ray Raman imaging (SXRI) technique. SXRI employs
a hard X-ray narrowband/broadband hybrid probe field and provides
a real-time and real-space image of the passage through conical intersections.
The signal, calculated using the minimal-coupling radiation/matter
Hamiltonian, carries the phase information, and the real-space image
of the transition charge density can be reconstructed by its Fourier
transform. The two conical intersections (S2/S1 (11ππ*/1πσ*) and S1/S0 (1πσ*/S0))
can be distinguished and identified by the diffraction patterns in
the level crossing regimes.
