The most interesting results of the work are as follows: 1) Form factors based on charge distribution density in atomic nuclei of different atomic weights are constructed and their influence on the formation of structure and shape of proton energy spectra formed in deuteron diffraction fission in nuclear and Coulomb fields is investigated. The most popular and widely used models of charge distribution in nuclei of different atomic weights are taken as the basis for the construction of form factors: a model with the potential of a harmonic oscillator was used for the lightest and lightest nuclei; two models of Helm (homogeneous Gaussian and homogeneous homogeneous) were used for medium and heavy nuclei; 2) The properties of bremsstrahlung photons emitted during the scattering of K-mesons on nuclei were studied for the first time. A new model of bremsstrahlung radiation for such scattering has been developed, on the basis of which high sensitivity of radiation spectra depending on internal mechanisms and the degree of penetration of kaons into nuclei has been revealed; 3) Based on a dynamic collective model, the beta decay of 133Xe -> 133Cs is described; 4) A new expression is obtained for the rate of coincidences in two-stage reactions that occur during high-energy central collisions of heavy ions; 5) A new method based on solving the Fokker-Planck equation has been proposed to study the dynamics of beams on storage rings using stochastic cooling. The stability of this method is investigated.
