Question

The edge unit cell in a cubic crystal is a = 2.62 Å. Find the Bragg angle corresponding to reflection from the planes (100), (110), (111), (200), (210), and (211), given that the monochromatic X-ray beam has a wavelength λ = 1.54 Å. The Cu target emits an X-ray line of wavelength 1.54 Å. Given that the Bragg angle for reflection from the (111) planes in Al is 19.29°.

Step 1

The Miller indices for a plane in a cubic crystal are determined by the intercepts of the plane with the crystallographic axes. For example, the (100) plane intercepts the x-axis at 1/a, the y-axis at 0, and the z-axis at 0. Therefore, the Miller indices for the Show more…
