Characteristic X-ray lines of different anode materials / Moseley’s law
Moseley’s law describes the relationship between the energy of the Ka lines of characteristic X-ray spectra and the atomic number. In this experiment, the characteristic X-ray lines of various different anode materials are determined in order to verify Moseley’s law.
