Selection Rules, Characteristic Lines and X-ray Spectra

1 hst a number of observed X-ray Hnes and their corresponding lUPAC and Siegbahn names. 

Moseley first estabUshed the relationship between the wavelength i of a characteristic X-ray photon and the atomic number Z of the excited element (see Fig. 

Each electron in an atom can be defined by four quantum numbers. The first of these quantum numbers is the principal quantum number n, which can take all integral values. When n is equal to 1, the level is referred to as the K level
