K alpha double splitting of molybdenum X-rays / fine structure
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.
