A simple procedure for evaluating the excitation energy and the spin transfer in heavyion dissipative collisions is proposed. It is based on a prediction of the GEMINI evaporation code : for a nucleus with a given excitation energy, the average number of emitted protons decreases with increasing spin, whereas the average number of alpha particles increases. Using that procedure for the reaction 107Ag+ 58Ni at 52 MeV/nucleon, the excitation energy and spin of quasiprojectiles have been evaluated. The results obtained in this way have been compared with the predictions of a model describing the primary dynamic stage of heavyion collisions. |
