Abstract
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.
