摘要：We report on the measurement of deep inner-shell 2 p X-ray photoelectron diffraction (XPD) patterns from laser-aligned I₂ molecules using X-ray free-electron laser (XFEL) pulses. The XPD patterns of the I₂ molecules, aligned parallel to the polarization vector of the XFEL, were well matched with our theoretical calculations. Further, we propose a criterion for applying our molecular-structure-determination methodology to the experimental XPD data. In turn, we have demonstrated that this approach is a significant step toward the time-resolved imaging of molecular structures.
