Abstract
A method for the calculation of many-electron wave functions of atoms and molecules is reported. The method is based on the orbital representation of the wave function and on the theory of perturbation with respect to the sum of attraction and repulsion potentials of electrons where the portion of the potential of attraction to the nuclei corresponds to the integral compensation of the attraction energy by the repulsion energy of the system of electrons. As examples, a number of atoms and the hydrogen molecule are calculated. The analytical view of the geminal representation of many-electron wave functions in the singular points of the electronic potential is discussed.
