Abstract
Exotic-deformation effects in 46Ti nucleus were investigated by analy- sing the high-energy -ray and the -particle energy spectra. One of the experiments was performed using the charged-particle multi-detector ar- ray ICARE together with a large volume (4 in×4 in) BGO detector. The study focused on simultaneous measurement of light charged particles and -rays in coincidence with the evaporation residues. The experimental data show a signature of very large deformations of the compound nucleus in the Jacobi transition region at the highest spins. These results are compared to data from previous experiments performed with the HECTOR array cou- pled to the EUROBALL array, where it was found that the GDR strength function is highly fragmented, strongly indicating a presence of nuclei with very large deformation.Pubblicazioni consigliate
