  A simple procedure for evaluating the excitation energy and the spin transfer
in heavy-ion 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
quasi-projectiles have been evaluated. The results obtained in this way have
been compared with the predictions of a model describing the primary dynamic
stage of heavy-ion collisions.
