Intervals of X-ray Spin-doublets

Abstract

The intervals of the X-ray spin-doublets are calculated for the L, M, and N terms of Cl, K, Ca, Cu, Rb and Cs atoms, on the basis of the Breit Hamiltonian. The eigenfunctions used in the computations involve the Hartree or the Hartree-Fock radial functions. The agreement between the calculated and the observed values is satisfactory in general
