摘要

In many problems of the nuclear physics at low energies and nuclear astrophysics the knowledge of the scattering elastic phase shifts, which can be determined from the differential cross sections of scattering of the various nuclear particles is required [1]. Such phase shifts are used, in particular, for construction of the intercluster interaction potentials, for example, in the potential cluster model (PCM) of easy light nuclei [2]. The procedure of the phase shift analysis consists in the decomposition of the total scattering amplitude in a row by the partial waves or amplitudes and the analysis of the parameters appearing at the same time, which are called the scattering phase shifts. Such phase shifts allow one to obtain the data about the nature of strong interactions, the structure of resonance states and the general structure of an atomic nucleus.
