N2 - A development of the RECP method for the case of transition and rare earth elements is suggested. New terms with projectors on the occupation numbers of d and f outermost shells respectively (which can be determined in SCF iterations) are added to the standard RECP operator and the corresponding "self-consistent" RECP terms are generated for atoms Cu, Ag and Au. Significant improvement is achieved in reproduction of atomic excitation energies as compared with the conventional shape-consistent RECP calculation.
