The figure below shows an x-ray diffraction pattern taken from a metal powder using a diffractometer and monochromatic x-radiation having a wavelength of 0.1542 nm; each diffraction peak on the pattern has been indexed. a. Determine the lattice parameter. b. Is this a bcc or an fcc metal? Justify your determination. c. Is the metal powder Cr, Co, Fe, or Ni?
