Strong Deformation Effects in Hot Rotating $^{46}$Ti

Abstract : Exotic-deformation effects in 46Ti nucleus were investigated by analysing the high-energy $\gamma$-ray and the $\alpha$-particle energy spectra. One of the experiments was performed using the charged-particle multi-detector array ICARE together with a large volume (4”×4”) BGO detector. The study focused on simultaneous measurement of light charged particles and $\gamma$-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 coupled 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.
