CONSTRUCTION OF ENERGY MATRIX FOR COMPLEX ATOMS IN-SPACE OF (ND-WI-WJ)N(I)L(I)(WI)N(J)L(J)(WJ) (WHERE W(I)+W(J)LESS-THAN-OR-EQUAL-TO-2) CONFIGURATIONS(N'S)(N+2)+SIGMA(I,J)ND(N+2)

A method of parametrization of interactions in the fine-structure of 3 d-atoms is extended to the model space of configurations (nd + n's)(N2) + (i,j)Sigma nd(N+2-wi-wj)n(i)(wi)n(j)l(j)(w)j. It accounts for the first- as well as the second-order effects of the perturbation theory . The close analogy to the parametrization of the hyperfine structure interactions is shortly discussed, this can serve as a sensitive test for the quality of fine structure analysis.
