In an XRD pattern using Cu Kα radiation, a certain cubic crystal
shows peaks at 2θ values (in degrees) of 44.3, 64.4, 81.6, 98.0. It
is known that the size of the cubic crystal is greater than 2.5
Angstroms. Based on this information and the location of the peaks,
we conclude that the lattice of the crystal is
1. simple cubic
2. face centered cubic
3. body centered cubic
4. none of
the other choices
