95. Experimental study of asymmetric nuclear matter EOS from heavy-ion reactions with RIBF-SPiRIT

ISOBE, Tadaaki (RIKEN)

Invited presentation

Neutron star (NS) is believed to be created as a remnant of supernova explosion. The property of neutron star can be described with the thermodynamical character (Equation of State, EoS) of nuclear matter.
For the determination of outer core NS-EoS, we have performed a series of measurements using heavy ion accelerator of RIKEN Radio Isotope Beam Factory (RIBF).
An international...

60. The INDRA-FAZIA setup: an overview of the most recent results on isospin transport phenomena

CIAMPI, Caterina (GANIL)

Invited presentation

Heavy-ion collisions in the intermediate energy regime (20-100 MeV/nucleon) are a widespread tool to probe the properties of nuclear matter far from equilibrium: among other topics, they allow to investigate isospin transport phenomena, which can be interpreted in the framework of the Nuclear Equation of State (NEoS), i.e. the thermodynamic description of nuclear matter.
The INDRA-FAZIA...

67. Nuclear symmetry energy and neutron stars

Nuclear Astrophysics

Invited presentation

The understanding of neutron star properties from fundamental physics is still far from being completed. One of the reasons is that the theory for strong force, QCD, does not apply simply to neutron star matter at a few times the nuclear saturation density. At low density, chiral effective field theory is fixing a limit which can be incorporated in the description of the crust of neutron...

48. Entrance channel effects in heavy-ion collisions within three-dimensional full dissipative dynamics

JAGANATHEN, Yannen (National Centre for Nuclear Research, Pasteur 7, Warsaw, Poland)

Nuclear Dynamics

Oral Presentation

We have thoroughly investigated the influence of entrance channel effects on the spin distribution and angular momentum in heavy ion collisions, employing three-dimensional dissipative dynamics. The microscopically derived Langevin equations were numerically solved using the distance, neck, asymmetry and the three angular macroscopic variables, which allow for an adequate description of the...

29. Study of the isospin transport phenomena in the 58Ni+58Ni reaction at 32, 52 and 74 AMeV with the FAZIA-INDRA apparatus.

BALDESI, Lucia (Dipartimento di Fisica e Astronomia Università di Firenze , INFN Sezione di Firenze)

Nuclear Dynamics

Oral Presentation

Heavy-ion collisions at Fermi energies allow to investigate various phenomena, such as the isospin transport phenomena. These can be interpreted in the framework of the Nuclear Equation of State (NEoS), which describes the properties of nuclear matter in terms of thermodynamic variables.
In this talk we will show the preliminary results of the study of the $^{58}$Ni+$^{58}$Ni reaction at...

14. Dynamics of cluster production in heavy ion collisions

GÉNARD, Tom (GANIL)

Nuclear Dynamics

Oral Presentation

Collisions of heavy ions are the best tools at our disposal to probe nuclear matter. It allows us to reach extreme densities, giving us the possibility to constrain transport models. In particular, at incident energies around 100 MeV/nucleon a participant zone is formed by a part of projectile and target nuclei.

The aim of this work is to characterize the participant zone. We will focus on...
