Abstract
We study the pre-equilibrium dipole response in the charge-asymmetric reaction Sn132+Ni58 at Elab=10MeV/A, within a semi-classical transport model employing effective interactions for the nuclear mean-field. In particular, we adopt the recently introduced SAMi-J Skyrme interactions, whose parameters are specifically tuned to improve the description of spin-isospin properties of nuclei. Within the same framework, we also discuss pre-equilibrium nucleon emission. Our results show that both mechanisms, i.e., pre-equilibrium dipole oscillations and nucleon emission, are sensitive to the symmetry energy below the saturation density Ï0 (in the range 0.6Ï0âÏ0), to the momentum dependence of the mean-field potential and to the nucleon-nucleon cross section. Finally, a correlation analysis is applied to examine the impact of the model parameters on observables of experimental interest.
