    Abstract

    Projectile - photon coincidences were measured for the scattering of an 80 MeV/nucleon Zn-64 beam from Pb-208 and Bi-209 targets at the GANIL heavy ion accelerator facility. Projectile-like particles between 0.5-degrees and 4.5-degrees relative to the incident beam direction were detected in the SPEG energy loss spectrometer where their momentum, charge, and mass were determined. Photons were detected in the BaF2 scintillation detector array TAPS. Light charged particles produced in the reaction were detected in the KVI Forward Wall.

    The analysis of the data acquired in this experiment is focused on three different phenomena: (1) the two phonon giant dipole resonance, (2) time dependence of the decay of the one phonon giant dipole resonance, and (3) giant resonance strength in projectile nuclei.
