Raman scattering in a d-wave superconductor - a one gap scenario

Recent Raman scattering data in B_{1g} and B_{2g} geometries in the superconducting state of underdoped cuprates were interpreted as evidence for two distinct energy gaps. We argue that these data can be equally well explained within a one gap scenario if final state interactions are taken into account. In particular, we show that they can account for the differing doping dependences of the Raman peaks in these two geometries.
