  There are also some references about Raman active modes for hcp metals
  (Fe, Zn, Zr, Mg) (Science 288, 1626 (2000))
  and a high-pressure metallic phase of oxygen (Phys. Rev. B 76, 64101 (2007).

  I was wondering how to obtain the Raman intensities for
  such "metallic"  materials.
  Any suggestion?

  Thank you very much,
