Omelchenko S. Investigation of coherent and dynamic effects in nuclear reactions within the framework of space-time analysis

In the thesis on the basis of the developed space-time analysis two methods are offered: (i) - space-time method which at calculations of cross-sections and velocities of coincidences considers available intermediate coherent channels in various classes of nuclear collision reactions and (ii) - a method of time resonances or a model of resonant decay (MRD) of an intermediate compound system over time, which is designed to calculate the anomalous inclusive spectra of the final fragments in some high-energy reactions. Within the framework of the space-time analysis, a method is proposed for calculating the cross sections for binary processes of nucleon scattering by light and medium nuclei, for collision reactions of light nuclei, as well as for non-peripheral collisions of heavy ions, with the importance of taking into account coherent effects everywhere emphasized. Within the MRD, calculations of inclusive spectra with atypical exponentially decreasing behavior with increasing energy for some high-energy reactions were performed, and the dynamics of decay of intermediate compound systems was studied. The thesis contains four scientific sections, of which the first three concern the use of space-time analysis to take into account the coherent intermediate channels of three types of reactions: (i) binary processes of nucleon scattering by nuclei, collision reactions (ii) light ions and (iii) heavy ions. The fourth section concerns the consideration of the above-mentioned MRD for the study of inclusive spectra of the selected final reaction products and the dynamics of non-exponential decay of intermediate compound-systems.
