Four different reactions, 32S+12C and 20Ne+12C at 25 50 MeV/nucleon, have been measured with the FAZIA detector capable of full isotopic identification most forward emitted reaction products. Fragment multiplicities, angular distributions energy spectra compared Monte Carlo simulations, i.e., antisymmetrized molecular dynamics (AMD) heavy-ion phase space exploration (HIPSE) models. These models are combined two afterburner codes (HFℓ SIMON) to describe decay excited primary fragments. In...
Isotopically resolved fragments with Z<=20 have been studied high resolution telescopes in a test run for the FAZIA collaboration. The were produced by collision of 84Kr beam at 35 MeV/nucleon n-rich (124Sn) and n-poor (112Sn) target. fragments, detected close to grazing angle, are mainly emitted from phase-space region projectile. fragment isotopic content clearly depends on n-richness target it is direct evidence isospin diffusion between projectile observed enhanced neutron richness light...
The modification of the ground state properties light atomic nuclei in nuclear and stellar medium is addressed, using chemical equilibrium constants evaluated from a new analysis intermediate energy heavy-ion (Xe+Sn) collision data measured by INDRA Collaboration. Three different reactions are considered, mainly differing isotopic content emission source. thermodynamic conditions samples extracted multiplicities allowing for parametrization in-medium modification, determined with single...
Experimental data concerning isospin transport phenomena for the systems $^{80}\mathrm{Kr}+^{40,48}\mathrm{Ca}$ at 35 MeV/nucleon are presented. Data have been collected with four FAZIA blocks; this set is same analyzed in S. Piantelli et al., Phys. Rev. C 101, 034613 (2020). The isotopic composition of QuasiProjectile residue (up to $Z$ around 25) and its decay products two reactions compared, finding a neutron enrichment when target $^{48}\mathrm{Ca}$. emitted light charged particles (LCP)...
The neutron-proton (n-p) equilibration process in $^{48}\mathrm{Ca}+^{40}\mathrm{Ca}$ at 35 MeV/nucleon bombarding energy is experimentally estimated by means of the isospin transport ratio. Experimental data are collected with a subset FAZIA telescope array, which permits us to determine $Z$ and $N$ detected fragments. For first time, quasiprojectile (QP) evaporative channel compared QP breakup one homogeneous consistent way, pointing comparable n-p equilibration, suggests close interaction...

Selecting from peripheral to semicentral collisions, both neutron content quasiprojectile residue that light ejectiles coming evaporation used as probes dynamical diffusion between projectile target for asymmetric...
We investigate the isospin transport with $^{40,48}\mathrm{Ca}+^{40,48}\mathrm{Ca}$ reactions at 35 MeV/nucleon, measured coupling of VAMOS high acceptance spectrometer and INDRA charged particle multidetector. Using fragment carefully selected light-charged-particles in coincidence INDRA, a reconstruction method is applied to estimate excited quasiprojectile (QP) on an event-by-event basis. Isospin diffusion investigated using ratio asymmetry $\ensuremath{\delta}=(N\ensuremath{-}Z)/A$...

This article presents an investigation of isospin equilibration in cross-bombarding $^{40,48}\mathrm{Ca}+^{40,48}\mathrm{Ca}$ reactions at 35 MeV/nucleon, by comparing experimental data with filtered transport model calculations. Isospin diffusion is studied using the evolution ratio centrality. The asymmetry parameter $\ensuremath{\delta}=(N\ensuremath{-}Z)/A$ quasiprojectile (QP) residue used as isospin-sensitive observable, while a recent method for impact reconstruction centrality...
In this work we provide a model-independent experimental evaluation of the degree isospin equilibration taking place in $^{58,64}$Ni+$^{58,64}$Ni collisions at 32 MeV/nucleon across varying reaction centralities. This result has been obtained by combining complementary information provided two different datasets, sharing common characteristics. The first dataset acquired with INDRA setup and used to implement reconstruction impact parameter. second campaign coupled INDRA-FAZIA apparatus...
We propose a Bayesian inference estimation of in-medium modification the cluster self-energies from light nuclei multiplicities measured in selected samples central ^{136,124}Xe+^{124,112}Sn collisions with INDRA apparatus. The data are interpreted relativistic quasiparticle approach mean-field approximation without any prior assumption on thermal parameters model. An excellent reproduction is obtained for H and He isotope multiplicities, compatible posterior distributions found unknown...
An abnormal production of events with almost equal-sized fragments was theoretically proposed as a signature spinodal instabilities responsible for nuclear multifragmentation in the Fermi energy domain. On other hand finite size effects are predicted to strongly reduce this production. High statistics quasifusion hot nuclei produced central collisions between Xe and Sn isotopes at 32 45 AMeV incident energies have been used definitively establish, through experimental measurement charge...
