Principle
The polychromatic molybdenum X-ray spectrum is analyzed by means of a monocrystal. The energy of the characteristic lines is determined from the positions of the glancing angles at various orders of diffraction. The separation of the K a doublet in higher order diffraction is examined.
Tasks
- Record the intensity of the X-rays emitted by the molybdenum anode as a function of the Bragg angle using a LiF monocrystal as analyzer.
- Determine the wavelengths and ratio of the intensities of the two K a lines in high order diffraction and compare your results with the theoretical predictions.
