Polysiloxane based scintillators with high light yield have been synthesized. The polymer consists in cross-linked polydimethyl-co-diphenylsiloxane different molar percentages of phenyl units. 2,5-diphenyl oxazole (PPO) and 2,5-bis(5-ter-butyl-2-benzoxazolyl)thiophene (BBOT) dispersed the as dopants. energy transfer scintillation capabilities investigated, for two amounts groups network concentrations dye molecules, by means fluorescence spectroscopy, ion beam induced luminescence (IBIL)...
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...
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)...
Polysiloxane-based scintillators are promising for employment in harsh environments, owing to their outstanding radiation resistance and thermal properties over the traditional plastics (polyvinyltoluene polystyrene). In this work, cross-linked polydimethyl-co-diphenylsiloxane (PMPS) with 22 % molar percentage of diphenylsiloxane units have been synthesised. 2,5-Diphenyloxazole Lumogen Violet (BASF) were employed as primary secondary fluor, respectively. Thermal neutrons sensitivity was...
Abstract The possibility to detect fast neutrons as a distinct signal from that one of γ-rays background is surely great importance for several topics, spanning homeland security radiation monitoring in nuclear physics research plants. Nowadays, Helium-3 based detectors are extremely expensive, while the use large volume liquid scintillators presents serious concerns related spillage risks and waste disposal. A very attractive alternative commercially available solid scintillators, which...
Isospin mixing in the hot compound nucleus 80Zr was studied by measuring and comparing γ-ray emission from fusion reactions 40Ca+40Ca at Ebeam=200 MeV 37Cl+44Ca Ebeam=153 MeV. The γ yield associated with giant dipole resonance is found to be different two because, self-conjugate nuclei, E1 selection rules forbid decay between states isospin I=0. degree of deduced statistical-model analysis spectrum emitted standard parameters 81Rb. results are used deduce zero-temperature value, which then...
Experimental results concerning the dynamical fission of quasiprojectiles in semiperipheral collisions for system $^{80}\mathrm{Kr}+^{48}\mathrm{Ca}$ at 35 MeV/nucleon are presented. Data have been collected with four blocks FAZIA setup first physics experiment Collaboration. The degree isospin equilibration between two fragments and its dependence on their charge asymmetry is investigated. data compared AMD model coupled to GEMINI as an afterburner, order get hints about timescale process.
The odd-even staggering of the yield final reaction products has been studied as a function proton (Z) and neutron (N) numbers for collisions 84 Kr+112 Sn Kr+124 at 35 MeV/nucleon, in wide range elements (up to Z ~ 20). experimental data show that effects rapidly decrease with increasing size fragments. Moreover N is definitely larger than one Z. Similar general features are qualitatively reproduced by GEMINI code. Concerning comparison two systems, rather similar, being slightly only...
The 12C + reaction at 95 MeV has been studied through the complete charge identification of its products by means GARFIELD+RCo experimental set-up INFN Laboratori Nazionali di Legnaro (LNL). In this paper, first a series two, comparison to dedicated Hauser–Feshbach calculation allows selecting set dissipative events which corresponds, large extent, statistical evaporation highly excited 24Mg. Information on isotopic distribution residues in coincidence with their chain is also extracted....
Multiple alpha coincidence and correlations are studied in the reaction $^{12}$C+$^{12}$C at 95 MeV for fusion-evaporation events completely detected charge. Two specific channels with Carbon Oxygen residues $\alpha$-particles addressed, which associated anomalously high branching ratios respect predictions by Hauser-Feshbach calculations. Triple emission appears kinematically compatible a sequential from highly excited Mg. The phase space distribution of $\alpha$-$\alpha$ coincidences...
High-energy giant dipole resonance (GDR) $\ensuremath{\gamma}$ rays were measured following the decay of hot, rotating compound nucleus $^{88}\mathrm{Mo}$, produced at excitation energies 124 and 261 MeV.

In this work, the performances of new red emitting phenyl-substituted polysiloxane based scintillators are described. Three dyes were dispersed in a phenyl-polysiloxane matrix order to shift scintillation wavelength towards part visible spectrum. PPO, Lumogen Violet (BASF) and Red mixed starting resins with different wt. % analysis samples was performed by means fluorescence measurements. The yield alpha particles at dye ratios monitored detecting either full spectrum or emitted light....
