1. Equilibration dynamics in nuclear reactions

Prof. Sait Umar (Vanderbilt University)

13/05/2019, 17:00

Invited

Low-energy heavy-ion reactions provide us a rich laboratory to study the equilibration dynamics of strongly interacting many-body systems. In particular, these reactions probe an intriguing interplay between the microscopic single-particle dynamics and collective motion at time scales too short for complete equilibration. In this presentation, we discuss recent microscopic studies of...

11. Phase transition dynamics in hot nuclei and N/Z influence

Dr Bernard BORDERIE (Institut de Physique Nucléaire IN2P3/CNRS)

Oral

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 extra production. High statistics quasifusion hot nuclei produced in central collisions between Xe and Sn isotopes...

90. Comparative study of four reactions at onset of pre-equilibrium emission

Magda Cicerchia (LNL)

Oral

The study of the emitted particles, comparing pre-equilibrium and thermal components, is a useful tool to examine the nuclear structure. Possible clustering effects, which may change the expected decay chain probability, could be highlighted on the competition between different reaction mechanisms. The NUCL-EX collaboration (INFN, Italy) has carried out an extensive research campaign on...
