| Abstract: | We report on experiments using the (α, α′ γ) method to investigate the structure of the Pygmy Dipole Resonance (PDR) in the nuclei ⁹⁴Mo, ¹²⁴Sn, ¹³⁸Ba and ¹⁴⁰Ce. The experiments were performed with the Big-Bite Spectrometer (BBS) at the KVI at an incident energy of Eα = 136 MeV. The method allows a clean separation of the PDR from other excitations in the same energy region by selecting the ground-state γ-decay channel. In addition, the high resolution of the γ-ray spectroscopy using high-purity Germanium detectors allows a state-to-state analysis even in the case of the rather high level density of the investigated nuclei. The comparison to (γ,γ′) experiments on the same nuclei reveals a splitting of the PDR into two groups of states with different underlying structure. |
