Description
We investigated entrance channel effects in the decay of excited 160Er and 164Yb, formed with 16O and 64Ni beams by measuring high energy (5--25 MeV) γ-ray spectra. Gamma rays from the decay of the giant dipole resonance (GDR) built on highly excited states provide a good probe to study these effects, since the γ rays are emitted in the early stages of the reaction. The γ-ray spectra measured in the 16O-induced reactions show the typical GDR bump whereas the γ-ray spectra from the more symmetric entrance channels show dramatically different shape. 22 refs., 5 figs., 2 tabs
