Cartoon of the RIXS experiment. A photon with energy and momentum impinges on the sample and another photon with energy and momentum leaves it. The conservation laws of energy and momentum are also highlighted, being ħω and q respectively the energy and momentum transferred to the sample.

Resonant inelastic X-ray scattering (RIXS) is an advanced X-ray spectroscopy technique.[1][2]

In the last two decades RIXS has been widely exploited to study the electronic, magnetic and structural properties of quantum materials and molecules. It is a resonant X-rays photon-in photon-out energy loss and momentum resolved spectroscopy, capable of measuring the energy and momentum transferred to specific excitations proper of the sample under study.[1][2]

The use of X-rays guarantees bulk sensitivity, as opposed to electron spectroscopies, and the tuning of the incoming X-rays to a specific absorption edge allows for element and chemical specificity.[1][2][3]

Due to the intrinsic inefficiency of the RIXS process, extremely brilliant sources of X-rays are crucial. In addition to that, the possibility to tune the energy of the incoming X-rays is compelling to match a chosen resonance. These two strict conditions make RIXS to be necessarily performed at synchrotrons or nowadays at X-ray free electron lasers (XFELs) and set the advent of third generation synchrotrons (1994, ESRF[4]) as a turning point for the success of the technique.[1][2]

Exploiting different experimental setups, RIXS can be performed using both soft and hard X-rays, spanning a vast range of absorption edges and thus samples to be studied.[1]
