TI - Imaging via Correlation of X-Ray Fluorescence Photons JO - Physical review letters VL - 130 IS - 17 SN - 0031-9007 CY - College Park, Md. PB - APS M1 - PUBDB-2022-06799 SP - 173201 PY - 2023 AB - We demonstrate that x-ray fluorescence emission, which cannot maintain a stationary interference pattern, can be used to obtain images of structures by recording photon-photon correlations in the manner of the stellar intensity interferometry of Hanbury Brown and Twiss. This is achieved utilizing femtosecond-duration pulses of a hard x-ray free-electron laser to generate the emission in exposures comparable to the coherence time of the fluorescence. Iterative phasing of the photon correlation map generated a model-free real-space image of the structure of the emitters. Since fluorescence can dominate coherent scattering, this may enable imaging uncrystallised macromolecules.
