K alpha double splitting of molybdenum X-rays / fine struc

Продукт No: P2540701

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

  1. 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.
  2. 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.

What you can learn about

  • Characteristic X-ray radiation 
  • Energy levels
  • Selection rules
  • Bragg equation
  • Energy term symbols
