Evidence for Spinodal Decomposition in Nuclear Multifragmentation

Abstract: Multifragmentation of a "fused system" was observed for central collisions between 32 MeV/nucleon 129Xe and (nat)Sn. Most of the resulting charged products were well identified due to the high performances of the INDRA 4pi array. Experimental higher-order charge correlations for fragments show a weak but nonambiguous enhancement of events with nearly equal-sized fragments. Supported by dynamical calculations in which spinodal decomposition is simulated, this observed enhancement is interpreted as a "fossil" si… Show more

“…In nuclear physics it plays a key role for nuclear multifragmentation where it gives rise to highly nonstatistical fragment size distributions with a preference for equal masses [7,8]. The present study is focussed on high-energy nuclear collisions and we have investigated the importance of spinodal decomposition while the expanding matter passes through the phase coexistence region.…”

“…Identifying fragments produced through spinodal decomposition is then of great importance to obtain informations about the homogeneous-matter energetics at sub-saturation density. Experimental indications of this mechanism in heavy-ion collisions have been obtained for instance through the analysis of size correlations [19,20]. We should note that the study of finite-size instabilities in homogeneous matter is complementary to the description of an equilibrated, clusterized system, as can be given at very low density by the virial equation of state [15] TABLE I: Saturation properties of the three Skyrme forces SLy230a, SGII and RATP.…”
