(Top raw) Snapshots of diamond during graphitization at different time instants after the FEL pulse irradiation corresponding to the absorbed dose of 0.8 eV/atom, photon energy of 47.4 eV, and FWHM pulse duration of 52.5 fs; reproduced from reference [10]. (Bottom raw) Powder diffraction patterns for the corresponding atomic structures obtained with X-ray photons of 1.54 Å.
