To investigate the synthesis of nuclei in pycnonuclear reactions in the dense medium of neutron stars based on the understanding of how a composite nucleus is formed during the collision of two nearest nuclei; to investigate the production of dileptons in proton-deuteron collisions at energies from 1 to 4 GeV, introducing the formalism of Dalitz decays and the previously developed formalism of proton-nuclear scattering; to simulate the interaction of accelerated ion beams with various materials, as well as to investigate thermal processes in the beam diagnostics system of the SIS100 cyclic accelerator (Fair, GSI); to continue studying the unconventional baryon structure in the light quark sector using the BGOOD photoproduction experiment (Bonn, Germany); to continue studying the photoproduction of strange mesons to describe the baryon resonance spectra and degrees of freedom in the low-energy non-perturbative QCD regime; to develop and apply a new multiparameter rating method for evaluating theories based on experimental data, to extend it to new observable quantities; to develop a highly accurate theoretical description of the full cross sections of neutron-free nuclear processes in a wide energy range; to develop a method for selecting and calibrating optimal macroscopic models of photon force functions and E1-dipole resonances in isotopic chains of Mo, Sn, Nd, Pb; to verify and develop a model of bremsstrahlung in spontaneous ternary fission of heavy nuclei with the release of an alpha particle; to apply our own modified diffraction theory, which takes into account longitudinal momentum transfers, as well as quantum chromodynamics methods to study the kinetics and dynamics of nuclear decay processes and describe the available experimental data; to verify and improve the strong absorption model, as well as the method of eikonal Green's functions, and apply them to describe nuclear reactions; to apply the dynamic collective model to study beta decay of nuclei.
