AI Article Synopsis
- Conventional RIXS instruments face challenges in obtaining high photon-count rates due to limited bandwidth of incident photons as energy resolution improves.* -
- The study reveals that RIXS spectra related to energy loss remain consistent regardless of the integration over incident energies during the core-hole lifetime.* -
- This finding allows RIXS equipment to leverage synchrotron radiation throughout the core-hole lifetime, enhancing energy-loss resolution while overcoming photon-count limitations.*
Article Abstract
Upon progressive refinement of energy resolution, the conventional resonant inelastic X-ray scattering (RIXS) instrumentation reaches the limit where the bandwidth of incident photons becomes insufficient to deliver an acceptable photon-count rate. Here it is shown that RIXS spectra as a function of energy loss are essentially invariant to their integration over incident energies within the core-hole lifetime. This fact permits RIXS instrumentation based on the hv-concept to utilize incident synchrotron radiation over the whole core-hole lifetime window without any compromise on the much finer energy-loss resolution, thereby breaking the photon-count limit.
