(Solved): 1 Powder diffraction pattems of three monatomic cubic crystals with BCC, FCC and diamond structure ...
1 Powder diffraction pattems of three monatomic cubic crystals with , FCC and diamond structures are recorded using a Debye-Scherrer camera. The angles in degrees of the first four diffraction lines for the three samples marked as are as under: (a) Determine the structure type of each sample. (b) What is the size of the cubic cell in each case? Take the wavelength of incident -rays as .
Expert Answer
Using the given diffraction angles and assuming a wavelength of 1.5 Å for the incident X-rays, we can determine the structure type of each sample and estimate the size of the cubic cell as follows: (a) Determine the structure type of each sample: To identify the structure type, we compare the observed angles with the expected angles for different crystal structures. Sample A: The observed angles for sample ...
