Abstract
The cross sections of excitation of the isovector giant dipole resonance in Sn-116, Sn-124 isotopes by inelastic scattering of alpha-particles in coincidence with gamma-decay into the ground state and the first excited 2+ state are presented. An attempt has been made to interpret a strong decay into the 2(1)+ state as a result of coupling of the giant dipole resonance (GDR) with the GDR built on the first 2+ state. For that, the microscopic calculation of the GDR fine structure has been performed within the quasiparticle phonon model. The results of calculations are in qualitative agreement with the experimental data.
