8.4. Powder diffraction experiment using a
CuK_(\alpha )line was carried out for a material in the range of
2\theta =20\deg -100\deg . The stable structure of this material is
BCCwith
a=3.42\angstrom . (a) State the positions of the observed peaks and from which planes they are coming. (b) Let's assume that the material is transformed into FCC struc- ture by application of a high pressure. Then, repeat "(a)".
