General positions of the unified theory of nuclear reactions and nuclear structure in formalism of quantum Green functions

The approach to the unified description of nuclear reactions and nuclear structure based on the formalism of the quantum Green functions and notions of the theory of the final Fermi systems is stated. The multiparticle effective forces of quasi-nucleon interactions in a nucleus are introduced. The T matrix of the nuclear reaction is presented in the form of expansion of a number of multiparticle collisions in a system up to its transition to a final state. It is shown that the T matrix and optical potentials along with wave functions of nuclei and secular equations are determined by the same structural vertices, being responsible for quasi-nucleon collectivization. The interpretation of the well-known method of strength functions is given
