Radiation damage yields across the carbon 1s excitation edge

X-rays are used as a probe in many materials analysis techniques, but they may induce changes in the sample that can invalidate the measurement. Strategies that overcome “radiation damage” are therefore desirable. Tuning the incident photon energy below a core electron excitation edge of a material (where only valence excitation takes place) rather than above it (where primarily core excitation occurs) has been theorized as a way to reduce …
