...Even though the secondary phase BaF2 was identified by Fourier-transform (FT) analysis (figure 2(c), BaF2 structure ICSD code 64717) and x-ray diffraction measurements [22], elemental maps obtained by STEM–EDXS or STEM–EELS often show an O signal instead of F as depicted in figure 2(c)....

...Simulations of diffraction patterns of possible O-containing phases like BaO (cubic, ICSD code 58663) and BaO2 (tetragonal, ICSD code 24729) show deviations compared to the experimental FT patterns....
