dd excitations of AgF2 measured by RIXS

We propose to perform the first-ever RIXS experiment at Ag L3 to study dd excitations in AgF2 single crystal, which has been recently predicted to become superconducting with an exceptionally high Tc of 200K if grown with a flat-layer structure different from the bulk one. Being able to use RIXS on it would be of the highest importance, in analogy to what has been done in the last decade of cuprates and iridates. Given some technical difficulties in handling AgF2 samples, and the availability of a medium resolution spectrometer for tender x-rays, ID26 is at present offering a unique opportunity to do this test experiment.
