As an example, we compare the direct RIXS signal below and above the superconducting transition for p-wave-type order parameters. For a p-wave order parameter with a nodal line, we show that, counterintuitively, the effect of the gap is most noticeable for momentum transfers in the nodal direction. This phenomenon may be naturally explained as a type of nesting effect.en-USJournal Article2019-09-2610.1103/PhysRevB.94.094516
