Phase transition dynamics for hot nuclei : a definitive answer

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 (...)

Mapping the demise of collective motion in nuclei at high excitation energy

D. Santonocito, Y. Blumenfeld, …, C. Monrozeau et al

Abstract High energy gamma-rays from the 116Sn + 24Mg reaction at 23A MeV were measured using the MEDEA detector at LNS – INFN Catania. Combining this new data with previous measurements yields a detailed view of the quenching of the Giant Dipole Resonance as a function of excitation energy in nuclei of mass A in the range 120&#xF7 ;132" role="presentation"> The transition towards the disappearance of the dipole strength, which occurs around 230 MeV excitation energy, appears to (...)

The extreme light infrastructure—nuclear physics (ELI-NP) facility : new horizons in physics with 10 PW ultra-intense lasers and 20 MeV brilliant gamma beams

Gales1,2, K A Tanaka1, D L Balabanski1, F Negoita1, D Stutman1,3, O Tesileanu1, C A Ur1, D Ursescu1, I Andrei1, S Ataman1

Show full author list The European Strategy Forum on Research Infrastructures (ESFRI) has selected in 2006 a proposal based on ultra-intense laser fields with intensities reaching up to 1022–1023 W cm−2 called ’ELI’ for Extreme Light Infrastructure. The construction of a large-scale laser-centred, distributed pan-European research infrastructure, involving beyond the state-of-the-art ultra-short and (...)

Systematic studies of correlations between different order flow harmonics in Pb-Pb collisions at √sNN=2.76 TeV

S. Acharya et al. (ALICE Collaboration)

The correlations between event-by-event fluctuations of anisotropic flow harmonic amplitudes have been measured in Pb-Pb collisions at √sNN=2.76 TeV with the ALICE detector at the Large Hadron Collider. The results are reported in terms of multiparticle correlation observables dubbed symmetric cumulants. These observables are robust against biases originating from nonflow effects. The centrality dependence of correlations between the higher order harmonics (the quadrangular v4 and (...)
