Abstract = {{We present a detailed analysis of resonant inelastic x-ray scattering
   from Fe1.087Te with unprecedented energy resolution. In contrast to the
   sharp peaks typically seen in insulating systems at the transition-metal
   L-3 edge, we observe spectra which show different characteristic
   features. For low-energy transfer, we experimentally observe
   theoretically predicted many-body effects of resonant Raman scattering
   from a noninteracting gas of fermions. Furthermore, we find that
   limitations to this many-body electron-only theory are realized at high
   Raman shift, where an exponential line shape reveals an energy scale not
   present in these considerations. This regime, identified as emission,
   requires considerations of lattice degrees of freedom to understand the
   line shape. We argue that both observations are intrinsic general
   features of many-body physics of metals.}},
