2. Elaborate on the meaning of the empirical constants An and b in "Moseley's law/rule" for Ka radiation on the basis of a "quasi-Bohr model generalization for heavy atoms", i.e. 2 electrons at most in the lowest orbit (with quantum number 1) before excitation. (2 points). Why is it justified to use the Rydberg energy for infinitely heavy nuclei in your elaboration? (1 point). Which physical constants are needed to explain the numerical value of An ?
