Nuclear expansion and symmetry energy of hot nuclei Academic Article uri icon


  • The decrease in the symmetry energy of hot nuclei populated in 58Ni + 58Ni, 58Fe + 58Ni and 58Fe + 58Fe reactions at beam energies of 30, 40 and 47 MeV/nucleon, as a function of excitation energy is studied. It is observed that this decrease is mainly a consequence of increasing expansion or decreasing density rather than the increasing temperature. The results are in good agreement with the recently reported microscopic calculation based on the Thomas-Fermi approach. An empirical relation to study the symmetry energy of finite nuclei in various mass regions is proposed. 2009 IOP Publishing Ltd.
