B. Borderie, N. Le Neindre, E. Galichet , P. Napolitani et al
An abnormal production of events with almost equal-sized fragments was
theoretically proposed as a signature of spinodal instabilities responsible for
nuclear multifragmentation in the Fermi energy domain. On the other hand finite
size effects are predicted to strongly reduce this abnormal production. High
statistics quasifusion hot nuclei produced in central collisions between Xe and
Sn isotopes at 32 and 45 AMeV incident energies have been used to definitively
establish, through the experimental measurement of charge correlations, the
presence of spinodal instabilities. N/Z influence was also studied.
