Below are listed diffraction angles for the first three peaks (first order) of the x-ray diffraction pattern for some metal. Monochromatic radiation having a wavelength of 0.1542nm was used.

1. Determine whether this metal’s crystal structure is FCC, BCC, or neither FCC nor BCC and explain the reason of your choice.
2. If the crystal structure is either BCC or FCC, identify which of the metals in the table gives this diffraction pattern.

 

Peak Order	Diffraction angle (2????)
1st	44.37
2nd	51.596
3rd	76.0884
