5fN configurations and x-ray spectra of actinides

The electronic structure of 5fN configurations and the characteristic X-ray radiation energies for an entire actinium series are calculated using the Hartree-Fock-Pauli approximation, and the variations obtained are analyzed. The electrostatic and magnetic parameters of these ions, as well as energies of their K and L lines, exhibit essentially nonlinear dependence on the nuclear charge and number of electrons. This fact evidences that simplified models of atomic structure are inapplicable to heavy ions
