Korda V. The theory of diffractive nuclear processes with deuterons, tritium, helium and lithium nuclei

Thesis is devoted to the development of general diffraction theory of interaction of light composite nuclei with nuclei. The common procedure accounting for the structure of complex hadrons is shown to limit the validity of the theory. The new method for visualizing nucleon-nucleus scattering matrices and the new technique for analytical calculations of the cross sections of the elastic and inelastic scattering and dissociation of light nuclei by nuclei are devised. Six models of the structure of 6Li nucleus are proposed. Permutationally invariant expressions for the integrated cross sections of the three-nucleon-nuclei–nuclei interaction processes are derived in the hyperspherical coordinates. The genetic algorithm with the negative selection pressure is devised to search for parameters of scattering matrix and to analyze spectra of quantum systems.
