AbstractAbstract
[en] Recently experiments were performed in Dubna (Russia) and RIKEN (Japan) to study 5H, 7H, and 8He. The 5H state at ∼ 1.8 MeV above the t + 2n threshold was observed in the reactions p(6He, 2He)5H and t(t,p)5H. The experimental evidence for existence of 7H state near the t + 4n threshold was obtained in study of the p(8He, 2He)7H reaction. Investigation of the p(8He, t) reaction populating the ground and excited 2+-state of 6He show that the 8He ground state has a structure containing the 6He subsystem in the excited 2+ state with a large weight

AbstractAbstract
[en] Data collection on the ''hot spot'' formation in nucleus-nuclear collisions and light particle emission from it is obtained. Some indications of the ''hot spot'' existence are received in the course of experimental data analysis - yield cross section of pre-equilibrium neutron escaping forward and spectra of light particles at backward angles. Calculations through the ''hot spot'' mechanism are compared with spectra. The forecast in respect to correlation experiment which may be considered as a critical one for the ''hot spot'' conception is drawn

AbstractAbstract
[en] The inclusive spectra of neutrons from reactions initiated by helium-, lithium- and carbon ions at energies above the Coulomb barrier from 1.6 up to 16 MeV/nucl. are analyzed. The neutrons are produced in the reaction with carbon at 1.6 MeV/nucl. energy as a result of evaporation from a compound nucleus. In all the other reactions the spectra deviation from the equilibrium behaviour is observed. Differential cross sections of neutron production were analyzed twice with the use of representation on the existence of angular-distributed energetic neutron sources. The obtained widths of non-equilibrium neutron, energy distributions cannot be explained by the simplest theories of projectile fragmentation and breakup reactions. These widths are explained in the framework of the exiton- and hybrid models of preequilibrium decay; the models correctly reproduce the form of experimental neutron distributions integrated over the angles, but do not coincide with them in the cross section absolute values. The relaxation times (1-4)x10-22 determined with the use of the hot spot model are in good agreement with the data obtained from the exiton model calculation. The period of the most intensive non-equilibrium emission turned out to be (1.5-3.5)x10-23 s in the hot spot representation and 4x10-23 s in the exiton representation. Comparison of the preequilibrium neutrons yield cross sections shows a possibility of the existence of the unified mechanism of preequilibrium decay in collisions with both heavy ions and light particles

AbstractAbstract
[en] Alpha spectra are investigated from the decay of 6Be ground (0+) and excited (2+) states into three-particles. For data analysis an approach is suggested, where binary formalism (R-matrix theory, decomposition with respect to efficient radius) is used for description of each pair of decay particles, and third particle effect is modulated by two-particle amplitude. As a result experimental data on both berillium state decay may be successfully described, factors influencing spectral shape are defined
