Study of cluster structures in¹⁰Be and¹⁶C neutron-rich nuclei via break-up reactions

Abstract

Projectile break-up reactions induced on polyethylene (CH 2 ) target are used in order to study the spectroscopy of 10 Be and 16 C nuclei. For the present experiment we used 10 Be and 16 C beams delivered by the FRIBs facility at INFN-LNS, and the CHIMERA 4π multi-detector. 10 Be and 16 C structures are studied via a relative energy analysis of break-up fragments. The 4 He+ 6 He break-up channel allowed us to study the spectroscopy of 10 Be; in particular we find evidence of a new state in

Experimental Studies of the Structure of $^{16}$C with Reactions at Intermediate Energy

“…This experiment, called CLIR (Clustering in Light Ions Reactions) has been devoted to the investigation of the structure of different unstable nuclei produced at LNS. The experimental apparatus was constituted by coupling the CHIMERA and FARCOS arrays [40], by using FARCOS for covering the most forward polar angles, where a large number of the projectile breakup fragments is expected [26]. FARCOS is a new generation array for correlations and spectroscopy developed by the CHIMERA Collaboration at LNS.…”

NArCoS: The new hodoscope for neutrons and charged particles

“…Particle-particle correlations are a relevant technique to pin down this kind of information [1][2][3][4][5][6]. By using light-charged particle (LCP) correlations, many works have been conducted from theoretical and experimental perspectives in nuclear dynamics and nuclear structure studies with correlators of first [7,8] and second generations, such as FARCOS [9][10][11][12][13][14]. Such correlation studies have also been explored for heavier charged particles, such as the intermediate mass fragments (IMFs), with an atomic number in the range 3 ≤ Z ≤ 25 [2,15], abundantly produced in heavy ion reactions.…”

Some Results for the Study of the Efficiency and Cross-Talk Probability by Using Geant4 Simulations for the Neutron Correlator Narcos

“…The neutrons in the plastic scintillator are prevalently (at these energies) seen as protons, for this reason, a DSSSD will be used as a veto detector in order to disentangle a primary proton from a primary neutron. The project will allow to design a secondgeneration neutron detector (but also light charged particles), aimed at working in a stand-alone mode or coupled to high-granularity 4π-detector systems like CHIMERA [2,19] or other light charged particle correlators like FARCOS [20][21][22][23][24][25] at National Laboratories of Sud in Catania (LNS). The neutron correlator is suitable for the incoming facilities for radioactive ion beams (RIBs) like, for example, FRAISE at INFN-LNS [26,27,28], SPES at National Laboratories of Legnaro (LNL) [29] and FAIR at GSI Darmstadt [30].…”
