Abstract

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