Radiative neutron capture on 9be, 14c, 14n, 15n and 16o at thermal and astrophysical energies

摘要

The total cross sections of the radiative neutron capture processes on 9Be,14C, 14N, 15N, and 16O are described in the framework of the modified potentialcluster model with the classification of orbital states according to Youngtableaux. The continued interest in the study of these reactions is due, on theone hand, to the important role played by this process in the analysis of manyfundamental properties of nuclei and nuclear reactions, and, on the other hand,to the wide use of the capture cross section data in the various applicationsof nuclear physics and nuclear astrophysics, and, also, to the importance ofthe analysis of primordial nucleosynthesis in the Universe. This article isdevoted to the description of results for the processes of the radiativeneutron capture on certain light atomic nuclei at thermal and astrophysicalenergies. The considered capture reactions are not part of stellarthermonuclear cycles, but involve in the reaction chains of inhomogeneous BigBang models.
