GLOBAL CHARACTERISTICS OF ATOMIC SPECTRA AND THEIR USE FOR THE ANALYSIS OF SPECTRA .4. CONFIGURATION-INTERACTION EFFECTS

Changes of the moments of atomic spectrum due to configuration interac tion (CI), the CI strength, the average shift of the energy of a level due to its interaction with all levels of distant configuration and o ther global characteristics of CI effects in atoms are systematised an d their expressions presented. The results of the calculation of these characteristics for the energy level spectra of the 3s3p(3) + 3s(2)3p 3d configurations in Si isoelectronic series, 3p(5)3d(N) + 3p(6)3d(N-2 )4p + 3p(6)3d(N-2)4f (N = 5, 6, 7, 8) in Cr, Mn, Fe and Co isoelectron ic series, ns(2) np(N) + np(N+2) at n = 2-5 and N = 2-4 in neutral ato ms as well as for the characteristic emission spectra corresponding to the 3p(5)3d(9) + 3d(7)4p --> 3d(8) transitions as well as for the Aug er M4,5N1N2,3 spectra in Kr and N4,5O1O2,3 in Xe are given and compare d with the same characteristics of the more complete experimental spec tra.
