In kinematics complete experiments the differential cross sections of many particle reactions d + 2H, d + 3H, 4He + 3H are received. It was established that mechanisms of double spin-flip and quasi free scattering of nuclei are dominated. The quantum characteristics of short lived nuclear states of 5He, 5Li and 8Be with time of life ~ 10-22 s are determined. For reactions with heavy ions the spatial anisotropy of short lived resonance parameters is confirmed. It is caused by the influence of Coulomb field of accompanying particles. In experiments with coincidence measurements the existence of strong deformed excitation of states of nucleuses 16О, 24Mg is established. The new isomeric states of nuclei 81Sr and 109In and their time of life are determined for the first t ime. The existence of dineutron cluster in 6Не was studied by the precise measurements of subbarrier elastic scattering of radioactive nuclei 6Не on 208Pb. The method of the analysis of angular distributions of heavy ions elastic scattering is developed to receive the cross sections of fusion reactions and total cross sections of periferical reactions. The connection of integrated break-up cross sections and total cross sections of the reactions 3Не + 58,64Ni with distribution of nuclear matter density was established. The strong sensitivity of Coulomb break-up of hyper helium-6 with bound energy of neutron and hyper helium-5 is theoretically predicted. The new classification of topological solitons and phase transitions between them are proposed. For the international experiment HERA-B the creation and test of multi target system of of B-mesons production at proton storage ring HERA (DESY, Hamburg, Germany) is completed with the purpose to study the combined parity violation in the decay channel B0 --> J/ps i + Ks0. The first events respected to this channel are identified. Product Description popup.authors popup.nrat_date 2020-04-02 Close
