Abstract
The gamma-ray spectra from the decay of the GDR in the compound nucleus reaction O-18 + Si-28 at bombarding energy of 105 MeV have been measured in an experiment using the EUROBALL IV and HECTOR arrays. The obtained experimental GDR strength function is highly fragmented, with a low energy (approximate to 10 MeV) component, indicating a presence of a large deformation and Coriolis effects. In addition, the preferential feeding of the highly-deformed band in Ca-42 by this GDR low energy component is observed.
