HEAVY ION EXCITATION AND PHOTON DECAY OF GIANT RESONANCES

Results are presented for excitation of giant multipole resonances by inelastic scattering of 350 and 400 MeV 16O projectiles from 90Zr and 208Pb. The giant quadrupole resonance is excited with large cross sections and a very large resonance peak to continuum ratio is obtained. Extracted cross sections agree with DWBA calculations which use standard collective model form factors. Using 380 MeV 17O to excite the giant resonances, the γ-ray decay has been measured for the giant quadrupole resonance region of 208Pb.
