  The 48Ti on 40Ca reactions have been studied at 300 and 600 MeV focusing on
the fusion-evaporation (FE) and fusion-fission (FF) exit channels. Energy
spectra and multiplicities of the emitted light charged particles have been
compared to Monte Carlo simulations based on the statistical model. Indeed, in
this mass region (A about 100) models predict that shape transitions can occur
at high spin values and relatively scarce data exist in the literature about
coincidence measurements between evaporation residues and light charged
particles. Signals of shape transitions can be found in the variations of the
lineshape of high energy gamma rays emitted from the de-excitation of GDR
states gated on different region of angular momenta. For this purpose it is
important to keep under control the FE and FF processes, to regulate the
statistical model parameters and to control the onset of possible
preequilibrium emissions from 300 to 600 MeV bombarding energy.
