Teijo A˚berg died on December 29, 2000 — and with his passing we have lost a gifted and important member of our community. Over the years Teijo has made many major contributions to the science of x‐ray and inner‐shell physics. Perhaps the most visionary of these was his idea of radiative and radiationless resonant Raman scattering (RRRRS) [1]. This arose as an outgrowth of his earlier thoughts on Auger [2] and x‐ray [3] processes. It is visionary in that it attempts to unify the various aspects of inner‐shell photoexcitation and decay as different aspects of the same basic process,i.e.resonant inelastic x‐ray scattering. In honor and memory of Teijo, and as a last attempt to promote his ideas, I describe here the theory and some of its consequences. First, RRRRS is outlined in a semi‐rigorous form, with emphasis placed on the physical nature of the concepts. Then, using the example of atomicK‐shell photoionization, we see how features such as fluorescence and photoelectron lines arise in a natural way as manifestations of resonance scattering. © 2003 American Institute of Physics
