Research report: 48 P., 19 Fig., 3 Tables., 30 Sources. The object of study – nuclear interaction of neutrons, tritons and alpha particles from deuterium, lithium, beryllium in a substance. The objective of phase 3 – conducting the initial experiments on interaction of charged particles and neutrons with light nuclei. Also identify the products of neutron-generating reactions using a beam of accelerated deuterons tandem-generator EGP-10K. The relevance and importance of the work: the results can be used to create a fundamentally new power plants. Research method - theoretical calculations and experimental studies. Prepared a measurement methodology for studies of the interaction of neutrons with matter mixed composition. The possibility of using existing infrastructure conducting neutron-physics tests with accelerated hydrogen ions on the beam charge-exchange electrostatic accelerator EGP-10K has been tested. Capabilities precision Metrology works with fast neutrons in the energy range from 3 to 18 MeV using the method of associated charged particles was proved. This is to get a "tagged" neutron spectrometry and time-of-flight without a pulse mode of operation of the accelerator can be used. Checked in correlation measurements of multifunctional detectorradio techniques are used for detailed search and analysis of peculiarities and mechanisms of interaction of neutrons with complex substance. The expediency of application of the method of transmission of slow neutrons is shown. Comparative analysis of experimental data for cross sections of interaction of neutrons with nuclei 54Fe at energies (from 0.3 to 26) MeV is made. The applicability of the optical-static approach and the method of coupled channels to the description of experimental total cross sections and cross sections for elastic and inelastic neutron scattering are investigated. The results of the adequate description of the totality of the experimental data used for the study in the examined energy range the contribution of the direct mechanism and the mechanism of scattering through a compound nucleus to the elastic and inelastic scattering of neutrons by nuclei 54Fe. The research results can be used by scientists and engineers who are engaged in the development of new alternative energy sources. The results of theoretical and experimental research can be the fundamental basis for the creation of a new method to extract nuclear energy with the prospect of a radically new power plants. Scope - Nuclear physics and energy.
