Question 3.70) Below are listed diffraction angles for the first four peaks (first-order) of the x-ray diffraction pattern for chromium, which has a BCC crystal structure; monochromatic x-radiation having a wavelength of 0.0711 nm was used.
Intensity (relative): 40.0, 50.0, 60.0, 80.0, 90.0
Plane Indices: (110), (200), (211), (220)
Diffraction angle: 20.0
a) Determine the interplanar spacing for each of the peaks.
Diffraction Angle: 20.1°, 28.5°, 35.1°, 40.8°
b) For each peak, determine the atomic radius for Cr, and compare these with the value presented in Table 3.1.
