“…The NUCLEX collaboration studies the behaviour of nuclear matter in a wide range of beam energies (5-100 MeV/nucleon) using different setups and particle identification techniques. This diversification is needed to better investigate phenomena typical of different energy regimes: compound nucleus formation and decay [62], α-clustering [63], charged particle spectroscopy [64], isospin transport mechanisms [65][66][67] and neck emissions [68]. Various setups have been developed and used at LNS, LNL and GANIL: FAZIA [69,70], GARFIELD [71], OSCAR [72] and the ACTAR demonstrator [73].…”

“…The enhancement at around 10 MeV comes from the contribution of the Pygmy Dipole Resonance decay of 68 Ni. The cross section of such Pygmy decay was evaluated from the difference between spectra measured in coincidence with 68 Ni and 66,67 Ni, as discussed in detail in Ref. [144].…”

Particle identification techniques are fundamental tools in nuclear physics experiments. Discriminating particles or nuclei produced in nuclear interactions allows to better understand the underlying physics mechanisms. The energy interval of these reactions is very broad, from sub-eV up to TeV. For this reason, many different identification approaches have been developed, often combining two or more observables. This paper reviews several of these techniques with emphasis on the expertise gained within the current nuclear physics scientific program of the Italian Istituto Nazionale di Fisica Nucleare (INFN).

“…A main advantage of AMD-like models is that they can address correlations dynamically. A detailed application of this approach can be found in References [60,61]. In this regard, the review article in Reference [62] is worth mentioning, which summarizes the present status of AMD and other transport approaches.…”

In this article we review the important role of non-equilibrium dynamics in reactions induced by ions and hadron beams to understand the fragmentation processes inside hadronic media. We discuss the single-particle dynamics in specific sources such as spectators in heavy-ion collisions and residual nuclear targets in hadron-induced reactions. Particular attention is given to the dynamics of hyperons. We further discuss the question regarding the onset of local instabilities, which are relevant for the appearance of fragmentation phenomena in nuclear reactions. We apply the theoretical formalism, that is, semi-classical transport embedded with statistical methods of nuclear fragmentation, to reactions induced by light ions and hadron beams. We discuss the results of nuclear fragmentation and, in particular, examine the formation of hypernuclei. Such studies are important for obtaining a deeper understanding of the equation of state in fragmenting matter and are relevant for forthcoming experiments, such as PANDA at FAIR and J-PARC in Japan.

“…Among these latter, a special focus has been put on the isospin transport phenomena [5]. Two main experimental observations in the field of isospin dynamics have been widely recognized by the scientific community: the process of isospin equilibration between reacting nuclei having different initial neutron-to-proton ratio N/Z [6][7][8][9][10][11][12][13][14][15][16][17], and the neutron enrichment of the midvelocity emissions [4,10,11,[14][15][16][18][19][20]. An interpretation of these two phenomena can be found in the framework of the Nuclear Equation of State (NEoS).…”

An investigation of the isospin equilibration process in the reactions 58,64 Ni+ 58,64 Ni at two bombarding energies in the Fermi regime (32 MeV/nucleon and 52 MeV/nucleon) is presented. Data have been acquired during the first experimental campaign of the coupled INDRA-FAZIA apparatus in GANIL. Selecting from peripheral to semi-central collisions, both the neutron content of the quasiprojectile residue and that of the light ejectiles coming from the quasiprojectile evaporation have been used as probes of the dynamical process of isospin diffusion between projectile and target for the asymmetric systems. The isospin transport ratio technique has been employed. The relaxation of the initial isospin imbalance with increasing centrality has been clearly evidenced. The isospin equilibration appears stronger for the reactions at 32 MeV/nucleon, as expected due to the longer projectile-target interaction time than at 52 MeV/nucleon. Coherent indications of isospin equilibration come from the quasiprojectile residue characteristics and from particles ascribed to the quasiprojectile decay.
