Paper Abstract

The difficulties associated with surface divergences, of a consistent QED theory in describing of the natural broadening (NB) of atomic systems are studied. This problem seems to be clearly and sensitively (in experimental meaning) appeared in the case of heavy multicharged ions. To overcome this difficulty we have used a quantity of elementary interaction length, an analogy of the length of coherence. We have obtained that the NB contains a linear l-divergence besides of a logarithmic one arising in standard QED calculations. A Z- dependence has allowed us to suggest carrying out the experimental testing of QED in the highly ionized atoms with the aid of more accurate technologies.
