The object of research - split reaction deuterons in heavy nuclei at energies pidbar'yernyh; deuteron splitting reaction to Triton at 36.9 MeV energy. Purpose - to investigate the mechanisms of splitting deuterons in different nuclei at different energies and kinematic conditions, to investigate the effect on sections of processes of splitting nuclei structural features and the interference of Coulomb and nuclear interactions and other factors. To develop appropriate models for the calculation of various nuclear reactions investigate the predictive capabilities of the proposed models by comparing calculations with experimental data. The method of research - calculation of reaction cross sections 1) by constructing interaction potential deuteron with the nucleus of a single model rolls; 2) using microscopic diffraction patterns and resonance model. The most interesting results of the work done are: 1. In the model of single rolls intended sections of elastic scattering of deuterons with energy 7, 7.3 and 8 MeV on nuclei 208Pb. Potential interactions in this system kernels konstruyuvavsya using complex potential dynamic polarizability. It is shown that taking into account the finite size of incident particles leads to a significant increase potentials in the peripheral region, which in turn makes it possible to significantly improve the coordination calculated differential cross sections of elastic scattering of experimental. 2. Experimental spectra and angular distributions of protons from the reaction T (d, p), measured at 36.9 MeV deuteron energy, described as satisfactory in form and in magnitude in the microscopic diffraction patterns involving nuclear mechanisms birth intermediate short-lived resonances * 4H at high energies vylitayuchyh protons and 4Ne * - for small. It is shown that the contribution of the birth process 4H resonances 4Ne * and * at small angles of departure of protons in the relevant section can reach 50%. However, with increasing angle of departure of protons main contribution to the angular distribution process will produce diffraction splitting deuterons in the field newts.
