    "abstract": "A method for the calculation of translationally invariant wave functions for\nsystems of identical fermions with arbitrary potential of pair interaction is\ndeveloped. It is based on the well-known result that the essential dynamic part\nof the Hamiltonian for the system of identical particles is the Reduced\nHamiltonian operator describing relative movement of two particles inside the\nsystem. The eigenfunctions of this operator take into account all correlations\ncaused by interaction. These eigenfunctions are basic for the construction of\nthe components (i.e. the functions with a lower degree of antisymmetry) of the\nsystem wave functions. The main problem of this approach appears to be\nantisymmetrization of the components. The developed universal algorithm for\nantisymmetrization gives a possibility to perform this operation in a simple\nway and keep numerical approximations under control.",
