Description
The Pygmy Dipole Resonance (PDR) has been investigated systematically using different experimental methods within the last years. Especially the comparison of results obtained using complementary probes revealed a deeper insight into the structure of the PDR [1,2]. Therefore, (a,a’g) experiments have been conducted at the Kernfysisch Versneller Instituut (KVI) in Groningen, The Netherlands using a primary beam energy of 136 MeV. In order to detect the scattered a particles in coincidence with the emitted gamma rays, the Big-Bite Spectrometer (BBS) and an array of High-Purity Germanium (HPGe) detectors were used [3].
The experimental setup will be discussed in detail as well as the high selectivity and the analyzing power of this method.
