Study of High-Lying States in Pb-208 with the Agata Demonstrator

An experiment aiming at the study of the gamma decay from the Giant Resonance region in the nuclei Pb-208, Zr-90 has recently been performed with the AGATA Demonstrator coupled to an array of large-volume scintillators (LaBr3:Ce, BaF2) to increase the overall gamma detection efficiency. The Pb-208 and Zr-90 nuclei were excited with inelastic scattering of O-17 at the incident energy of 20 MeV/u. The ejectiles were detected in a pair of silicon E-Delta E telescopes placed at forward angles. Preliminary results concerning the first partial analysis of the measurement with the Pb-208 target are here presented.
