Abstract

In this proceeding we present recent results concerning the study of the symmetry energy coefficient of finite nuclei with 40,48Ca+40,48Ca peripheral to semi-peripheral reactions at 35 MeV/nucleon. Data were obtained using the unique coupling of the VAMOS high acceptance spectrometer and the INDRA detector. VAMOS allowed high resolution measurement of charge, mass and velocity of the cold projectile-like fragment (PLF), while the INDRA detector recorded coincident charged particles with nearly 4π acceptance. This coupling allows reconstructing the mass, charge and excitation energy of the associated initial quasi-projectile nuclei (QP), as well as the extraction of apparent temperatures. The isoscaling method was applied with the fragment identified in VAMOS and the experimental reconstructed QP, in order to estimate the surface to volume contribution of the symmetry energy term of finite nuclei.
