Q. |
The Miller indices h, k, and l of parallel planes in a BCC lattice should satisfy which of the following X-ray diffraction reflection rules? |
A. | h + k + l should be even |
B. | h, k, and l should all be either even or odd |
C. | h, k, and l should form pythagoras triplet |
D. | all planes allow reflections view answer |
Answer» A. h + k + l should be even | |
Explanation: if the sum of miller indices becomes odd for a bcc lattice, destructive interference occurs. |
