# Deformation Effects in Hot Rotating $^{46}$Ti Probed by the Charged Particle Emission and GDR gamma-Decay

Abstract : The $^{46}$Ti* compound nucleus, as populated by the fusion-evaporation reaction $^{27}$Al+$^{19}$F at the bombarding energy of E_{lab}=144 MeV, has been investigated by charged particle spectroscopy using the multidetector array ICARE at the VIVITRON tandem facility of the IReS (Strasbourg). The light charged particles and high-energy gamma-rays from the GDR decay have been measured in coincidence with selected evaporation residues. The CACARIZO code, a Monte Carlo implementation of the statistical-model code CASCADE, has been used to calculate the spectral shapes of evaporated alpha-particles which are compared with the experimental coincident spectra. This comparison indicates the signature of large deformations (possibly superdeformed and hyperdeformed shapes) present in the compound nucleus decay. The occurrence of the Jacobi shape transition is also discussed in the framework of a newly developed rotating liquid drop model.
