Cross sections were compared with distorted wave Born approximation predictions and in general a good agreement was found. The measured energy and intensity distributions of the 2(+) states are very similar to the predictions based on self-consistent density functional theory and extended QRPA approach accounting for multiphonon degrees of freedom. This provides evidence of the excitation of the pygmy quadrupole resonance in skin nuclei. %R 10.1103/PhysRevC.92.014330 %U https://doi.org/10.1103/PhysRevC.92.014330 %P 014330-7pp
