Problem 1 25 Points An X Ray Diffractometer Recorder Chart For A Metal Sample Showed The First Six Diffraction Peaks A 1 (1.1 MiB) Viewed 46 times

Problem 1 (25 points) An x-ray diffractometer recorder chart for a metal sample showed the first six diffraction peaks at the following 20 angles: 43.632°, 44.716°, 50.826°, 74.750°, 90.671° and 95.990º. (The wavelength of the incoming X-ray radiation was 0.15405 nm). (a) Can one conclude that all six diffraction peaks are from either a BCC or an FCC crystalline solid? Justify your answer. (b) If excluding the diffraction peak No.2, can one conclude that the remaining five diffraction peaks are from either a BCC or an FCC crystalline solid? Justify your answer. (c) Can you speculate why there is the diffraction peak No.2 in the metal sample? 600 400 Intensity (cps) 2 200 4 Сл 6 0 30 50 90 70 20 (deg)
