Abstract = {{The Borrmann effect is the anomalous transmission of x-rays in perfect
   crystals under diffraction conditions. It arises from the interference
   of the incident and diffracted waves, which creates a standing wave with
   nodes at strongly absorbing atoms. Dipolar absorption of x-rays is thus
   diminished, which makes the crystal nearly transparent for certain x-ray
   wave vectors. Indeed, a relative enhancement of electric quadrupole
   absorption via the Borrmann effect has been demonstrated recently. Here
   we show that the Borrmann effect has a significantly larger impact on
   resonant x-ray emission than is observable in x-ray absorption. Emission
   from a dipole forbidden intermediate state may even dominate the
   corresponding x-ray spectra. Our work extends the domain of x-ray
   standing wave methods to resonant x-ray emission spectroscopy and
   provides means for novel spectroscopic experiments in d- and f-electron
   systems.}},
