Giant dipole resonance is a collective excitation of atomic nuclei. In the macroscopic interpretation giant dipole resonance is a collective oscillation of all protons against all neutrons in a nucleus. Giant dipole resonance occurs systematically in most nuclei with energies typically in the range of 10–30 MeV. GDR is an efficient tool to probe nuclear properties, for study of structure and dynamics of atomic nuclei, nuclear reaction mechanism.
Show AbstractAn asymptotic expansion of the solution of a boundary value problem for a system of two ordinary differential equations in the form of step-type contrasting structures was built. Using the method of differential inequalities, was proved the existence of the considered problems of decisions of this type, for which the built decomposition is constructed asymptotic approximation.
