Abstract
Variants of the construction of the effective Hamiltonian for valence elect rons of an atom are discussed. It is shown that a proper choice of the opti mum initial approximation can substantially improve the agreement between c alculated and experimental spectra of multielectron atoms. The optimized ef fective Hamiltonian can be used for calculations of atomic quantities.
