Abstract The structural transformations induced in cubic (C-type) Gd 2 O 3 irradiated with low-energy (4 MeV Au, ballistic regime) or high-energy (∼100 MeV Pb or Xe, electronic excitation regime) ions have been studied via the combination of X-ray diffraction (XRD) and Raman spectroscopy. Results show that Gd 2 O 3 undergoes a monoclinic (B-type) phase transformation in both ion irradiation regimes. Nevertheless, significant differences are observed: (i) with low-energy ions the B-type… CONTINUE READING
