Gakh A. Internal structure of the 2H, 3H, 3He and 4He nuclei and their diffraction interaction with heavy nuclei

Object of research: the internal structure of the 2H, 3H, 3He and 4He nuclei and the processes of their diffraction interaction with nuclei in the energy range of 40-75 MeV/nucleon. The aim: the development of the new physical approaches for realistic wave functions of the light nuclei building and analyses of these nuclei's internal structure influence on the values of differential and integrated cross sections of the different diffraction processes of their interaction with heavy nuclei in the energy range of 40-75 MeV/nucleon. Methods: theoretical calculations of light nuclei electromagnetic form factors were done using known formulas, connected the square of the wave function of the nucleus ground state (charge density distribution) with its form factor. The wave function parameters were defined by comparison of the calculated and measured electromagnetic form factors wit the help of genetic algorithm. The nucleus-nucleus interaction analysis is carried out taking into account the internal structure of the incident particles and the Coulomb interaction in the diffraction approximation with the Ericson parameterization for the nucleon-nucleus profile functions. Results: For the first time the deuteron ground state wave function was built on the basis of the experimentally measured charged and quadrupole form factors, the binding energy, the mean square radius and the quadrupole moment of the deuteron. For the first time the realistic ground state wave functions of the three-nucleon nuclei were built on the basis of the experimentally measured charged form factors, the binding energies and the mean square radius. For the first time it was proved that taking into account the light nuclei internal structure using the realistic wave functions in the analyses of the experimentally measured differential cross sections of these nuclei elastically scattered by heavy nuclei in the frame of diffraction model was important for correct definition of the target nucleus parameters. The field of application: nuclear physics research.
