150Sm were used to form the same composite system with A ∼ 160 at about 300 MeV of excitation energy, as derived from measurements of both the linear momentum transfer and the neutron multiplicity. The comparison of the evaporative spectra of the α particles in coincidence with evaporation residues does not show evidence for effects related to the entrance channel of the reaction, such as those predicted by dynamical models.
