Karazin popup.description2 Objects of research - the structure of light nuclei, the mechanism of interaction of alpha-particles with magnesium nuclei, a model of strong absorption with an anti-symmetrized S-matrix. Properties of Fermi and Bose quasiparticles and their interaction in superfluid helium and crystalline lattice, oscillations of metal magnetization. The subject of the study are the calculation of cross sections for the interaction of alpha particles with magnesium nuclei, the development of a theoretical description of the effects of nuclear rain-scattering, and the development of a strong absorption model with an antisymmetric S-matrix. Investigation of the oscillatory nature of the magnetization of metals in an external magnetic field at low temperatures, the relationship between these oscillations with quantum diffraction. The purpose of the work are to modify the new original parametrization of the scattering matrix and to determine the structural nuclear parameters by folding the experimental data. Also, the aim is to study the effects of oscillations in metals under the influence of external fields. The exact analytical expressions for the damping coefficient are obtained, which determines the amplitude of elastic scattering and the full cross section for interaction, reactions and elastic scattering. The study of the oscillatory nature of the magnetization of metals in an external magnetic field at low temperatures is performed, and the connection of these oscillations with quantum diffraction is established. The quantum interpretation of the de Haaz - van Alfen model of metal magnetization oscillations is considered, and the effects of oscillations in metals under the action of external fields are investigated.
