The γ decay of the pygmy dipole resonance of 124Sn was measured with the AGATA demonstrator coupled to an array of 9 large volume LaBr3:Ce scintillators. This resonance was populated by the inelastic scattering reaction 17O+124Sn at 20 MeV/u. With AGATA, the γ decay up to the neutron separation energy was measured with high resolution. The angular distribution was measured both for the γ rays and the scattered 17O ions. The present results are presented in comparison with the previous findings for (γ, γ') and (α,α'γ).

Abstract
The γ decay of the pygmy dipole resonance of 124Sn was measured with the AGATA demonstrator coupled to an array of 9 large volume LaBr3:Ce scintillators. This resonance was populated by the inelastic scattering reaction 17O+124Sn at 20 MeV/u. With AGATA, the γ decay up to the neutron separation energy was measured with high resolution. The angular distribution was measured both for the γ rays and the scattered 17O ions. The present results are presented in comparison with the previous findings for (γ, γ') and (α,α'γ).
