Object of research is elastic and inelastic scattering and fission of low-energy deuterons on nuclei; bremsstrahlung of photons in scattering of protons on nuclei in region of delta resonance birth energies; weakening of weak interaction in nuclei, collision of pairs of identical α-cluster nuclei. The most interesting of the results of the work are: 1. A large number of formulas expressing the differential cross sections of the response of elastic (inelastic) scattering and fission of deuterons when they collide with atomic nuclei, through the corresponding elements of T-matrices and F-amplitudes in the laboratory system and center of mass system. An important relationship between the T-matrix approach and the diffraction approximation has been established. Numerical calculations of reaction cross sections and comparison of these results with the experiment were performed. 2. For the first time, delta resonances in nuclei on basis of analysis of bremsstrahlung in proton-nucleus scattering is studied, search for nuclei with the strongest effect of delta resonance in nuclei on photon emission is performed for future experiments. 3. It is found that for a correct description of the probabilities of beta decay with renormalization of weak forces, and for a successful description of experimental values ​​for nuclei in the region A = 31 - 231 in the calculations it is necessary to take into account the 10th term in the Hamiltonian matrix element. 4. Within model scheme "direct + delayed" macroscopically indistinguishable process, where intermediate process of nuclear molecule formation was used as a detainee, cross sections of 12C + 12C and 16O + 16O were calculated within approximation of space-time analysis with moments J = 6 for 12C+ 12C in energy range 5-37 MeV and for 16O + 16O in energy 19-21 MeV.
