Abstract
The gamma-rays following the reaction 105 MeV O-18+Si-28 have been measured using the EUROBALL IV, HECTOR and EUCLIDES arrays in order to investigate the predicted Jacobi shape transition. The high-energy gamma-ray spectrum from the GDR decay indicates the presence of large deformations in the hot Ti-46 nucleus, in agreement with new theoretical calculations based on the rotating liquid-drop model.
