At the Laboratori Nazionali del Sud of INFN (INFN-LNS) in Catania, construction new Radioactive Ion Beams (RIBs) facility FRAISE (FRAgment In-flight SEparator) has reached its ending phase. The uses in-flight technique based on a primary beam fragmentation impinging light Be or C targets. makes use and medium mass beams, having power up to ≈ 2–3 kW, leading RIBs, whose intensities vary range 10 3 –10 7 pps, for nuclei far from close stability valley, respectively. aims at providing...
Background: The $\ensuremath{\gamma}$ decay of $^{12}\mathrm{C}$ levels above the particle emission threshold plays a crucial role in production astrophysical environments. Hoyle state is fundamental helium-burning phase red giant stars, while 9.64-MeV level can be involved higher temperature explosive environments.Purpose: aim this work was to explore feasibility measuring $\ensuremath{\gamma}$-decay widths state. experiments were performed at Laboratori Nazionali del Sud INFN (INFN-LNS),...
Proper detection of neutrons and charged particles is motivated by the recent efforts to construct new facilities for radioactive ion beams (RIBs) worldwide. Detection an important opportunity improve our understanding nuclear spectroscopy reaction dynamics, with possibility constraining theoretical models equation state (NEoS) investigating in-medium interactions. This topic also has implications in study astrophysical objects, such as neutron stars. In this work, state-of-the-art Neutron...
An investigation plan of different clustering and molecular states in neutron rich isotopes Lithium, Beryllium, Boron Carbon, the context an experimental campaign at INFN-Laboratori Nazionali del Sud, is presented. High statistics new information on known study will be possible thanks to high intensities available for exotic beams, delivered by FRAISE facility opportunity using very performing apparatus, as well detectors CHIMERA, FARCOS, NArCOS. Among these, hodoscope NArCOS, detecting with...
Radioactive Ion Beams (RIBs) of large intensity (10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6</sup> pps or higher) are at the frontier in nuclear physics and available since one decade different facilities new ones presently under construction. The paper illustrates conception a novel detection system for RIBs diagnostics tagging presents detailed analysis to access feasibility proposed together with design dedicated readout system.
We describe the search of Efimov state in 12 C performed by analysing a large set 3-α particles coincidence data measured at LNS laboratories with CHIMERA detector. The are compatible presence an excitation energy 7.485 MeV, probability smaller than 0.3% population Hoyle state. gamma decay should be around 30%, much larger one this level is Suda limit for reaction rate stars because its possible only through direct reaction. More investigations improving detector angular resolution needed to...
An investigation of the influence isospin (N/Z ratio) on thermometric characteristics, in reactions 78 Kr+ 40 Ca and 86 48 at 10 AMeV is presented. The experiment was performed INFN Laboratori Nazionali del Sud Catania by using beams delivered Superconductive Cyclotron 4 π multidetector CHIMERA. effects decay modes two produced composite systems competition between statistical dynamical break-up projectile have been studied. thermal evaporation from both compound nucleus (CN)...
In this contribution the connection between Dipolar degree of freedom excited in Heavy Ion Collisions through pre-equilibrium dipolar modes and Isospin-equilibration processes is discussed. The leads to definition a new observable so called “dipolar signal”, able describe equilibration process momentum space related final fragmentation produced by HIC. Preliminary results on measured system 48 Ca + 27 Al at 40 MeV/nucleon corresponding different degrees dissipation/centrality are presented....

A comparative study of the quasielastic barrier distributions 20 Ne+ 92,94,95 Mo systems was performed at Heavy Ion Laboratory (HIL) University Warsaw.The experiment aimed to influence dissipation due single-particle excitations on distribution structure.The preliminary results indicate that larger number singleparticle for heaviest isotopes leads smoothing distribution, which loses structure foreseen by coupling only collective excitations.Theoretical calculations including non-collective...
The physics of clusters in heavy neutron-rich ions is a topic constant interest the worldwide scientific community. In recent times, many interesting phenomena have been investigated especially thanks to development new radioactive beam production facilities. One example clustering α particles isotopes self-conjugated nuclei, such as 10 Be or 16 C, exhibiting even very large nuclear deformations. At Laboratori Nazionali del Sud INFN, study was carried out on clustering, employing CHIMERA and...
