The subject matter of this work is driven by the observed significant discrepancies between the results of the experiment and the results of calculations obtained within the commonly accepted theoretical models of hyperfine interactions. Consequently, this work concerns the development of hyperfine structure model that will enable for a full separation of contributions from one-body interactions (I approximation of perturbation theory) as well as from two-body interactions (II approximation of perturbation theory) to the observed splittings of hyperfine electron levels that belong to the systems developed by the configurations with a number of open shells. The proposed theory of parametrization of two-body interactions in hyperfine structure constitutes a generalisation of our hitherto works [1] and will allow for analysing each configuration system, really existent in the atom nlN−1(n’l’+ n"1" + n”’l”’)3. An enhanced model of the description of hyperfine interactions will be applied to interpret the experimental results for selected atoms. [1]J.Dembczyski,W.Ertmer,U.Johann and P.Unkel,Z.Phys.
