Dynamical effects on the quasiprojectile temperature in the Ar + Al reaction

The temperature of the quasiprojectile (QP) emerging from binary collisions of the light Ar+Al system at 65 MeV/nucleon is studied theoretically in the framework of the Landau-Vlasov dynamical model. The slope parameter of a charged-particle kinetic-energy spectrum, calculated in the forward-hemisphere of the QP reference frame, is taken as the apparent temperature. The apparent temperature associated to the true QP emission displays a weak dependence on the impact parameter and the hottest primary QPs are formed at intermediate values of b. (orig.)
