K- and L-absorption edges of X-rays / Moseley's Law and the Rydberg constant
Principle: Samples of various elements of different atomic numbers are to be irradiated with X-rays of a known spectral distribution, and the energy of the transmitted intensities analysed using a monocrystal analyzer. The Rydberg constant and screening constants are to be found by determining the energy at which absorption edges occur.
Tasks:
1. The intensity of the X-rays emitted from the copper anode is to be recorded as a function of the Bragg angle using an LiF monocrystal as analyzer.
2. The K absorption edges of different absorber materials are to be found.
3. The Rydberg and screening constants are to be calculated from the energy values of the K absorption edges.
4. The L absorption edges of different absorber materials are to be found.
5. The Rydberg constant is to be calculated from the energy values of the L absorption edges.
