[hal-01833663] Understanding the thermometry of hot nuclei from the energy spectra of light charged particles
14 juillet, par ano.nymous@ccsd.cnrs.fr.invalid (E. Vient), E. VientIn the Fermi energy domain, the temperature of hot nuclei can be determined using the energy spectra of evaporated light charged particles. But this method of measurement is not without difficulties both theoretical and experimental. The present study aims to disentangle the respective (...) -
[hal-01807031] Phase transition dynamics for hot nuclei
14 juillet, par ano.nymous@ccsd.cnrs.fr.invalid (B. Borderie), B. BorderieAn 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 (...) -
[in2p3-00009760] New method for the discrimination of single-source events in heavy-ion collisions
19 juin, par ano.nymous@ccsd.cnrs.fr.invalid (P. Desesquelles), P. DesesquellesThis paper introduces a new method for the selection of central single-source events, based on classical multivariate techniques. The resulting discriminating variable is shown to be valid for different hypotheses on the nuclear source deexcitation mechanism. It enables the selection of events (...) -
[in2p3-00003596] Mass scaling of reaction mechanisms in intermediate energy heavy ion collisions
19 juin, par ano.nymous@ccsd.cnrs.fr.invalid (V. Metivier), V. MetivierReaction mechanisms have been studied for two nearly symmetrical systems of different total mass, between 25 and 74 AMeV. It is shown that collisions are mostly binary whatever the system mass and the bombarding energy. From the slowing-down of the partners, it is possible to establish the (...) -
[in2p3-00010822] Emission time scale of light particles in the system Xe+Sn at 50 A.MeV - A probe for dynamical emission ?
19 juin, par ano.nymous@ccsd.cnrs.fr.invalid (D. Gourio), D. GourioProton and deuteron correlation functions have been investigated with both impact parameter and emission source selections. The correlations of the system 129Xe+NatSn at 50 AMeV have been measured with the 4π INDRA which provides a complete kinematical description of each event. The emission (...)
