1. The problem statement, all variables and given/known data
The von Laue condition for x ray diffraction can be written dΔκ =2πn where d is a displacement vector between indentical atoms and n an integer What is the smalest angle θ through which x -rays of wavelength 0.12 nm may be scattered by a sample of polonium ,a simple cubic crystal with a = 0.335 nm ?
2. Relevant equations
Can anybody give me the equation i need, or a reference to look ?
3. The attempt at a solution
