Abstract

Direct measurements of reaction cross-sections at astrophysical energies often require the use of solid targets able to withstand high ion beam currents for extended periods of time. Thus, monitoring target thickness, isotopic composition, and target stoichiometry during data taking is critical to account for possible target modifications and to reduce uncertainties in the final cross-section results. A common technique used for these purposes is the Nuclear Resonant Reaction Analysis (NRRA), which however requires that a narrow resonance be available inside the dynamic range of the accelerator used. In cases when this is not possible, as for example the $$^{13}\hbox {C}(\alpha ,\hbox {n})^{16}\hbox {O}$$ reaction recently studied at low energies at the Laboratory for Underground Nuclear Astrophysics (LUNA) in Italy, alternative approaches must be found. Here, we present a new application of the shape analysis of primary $$\gamma $$ rays emitted by the $$^{13}\hbox {C}(\hbox {p},\gamma )^{14}\hbox {N}$$ radiative capture reaction. This approach was used to monitor $$^{13}\hbox {C}$$ target degradation in situ during the $$^{13}\hbox {C}(\alpha ,\hbox {n})^{16}\hbox {O}$$ data taking campaign. The results obtained are in agreement with evaluations subsequently performed at Atomki (Hungary) using the NRRA method. A preliminary application for the extraction of the $$^{13}\hbox {C}(\alpha ,\hbox {n})^{16}\hbox {O}$$ reaction cross-section at one beam energy is also reported.

Abstract

International audience; Sub-barrier fusion of the two near-by systems$^{36}$S +$^{50}$Ti,$^{51}$V has been measured at the Laboratori Nazionali di Legnaro (INFN). Motivation for the experiment came from the possible effect of the non-zero spin of the ground state of the$^{51}$V nucleus on the sub-barrier excitation function, and in particular on the shape of the barrier distribution. No previous data were available for these two systems near the barrier. Our results show that the two measured excitation functions are very similar down to the level of 20-30μb. The same is true for the two barrier distributions. Coupled-channel calculations have been performed including the low energy excitations of both projectile and the two targets. We have indication that the low-lying levels in$^{51}$V can be interpreted in the weak-coupling scheme, that is,$^{51}$V (I) =$^{50}$Ti(2$^{+}$) ⊗ p(1f$_{7/2}$) and that the extra proton in the $ 1f_{7/2}$ shell does not have a significant influence on sub-barrier fusion.

Abstract

Materials containing radionuclides of natural origin, which is modified by human made processes and being subject to regulation because of their radioactivity are known as NORM. We present a brief review of the main categories of non-nuclear industries together with the levels of activity concentration in feed raw materials, products and waste, including mechanisms of radioisotope enrichments. The global management of NORM shows a high level of complexity, mainly due to different degrees of radioactivity enhancement and the huge amount of worldwide waste production. The future tendency of guidelines concerning environmental protection will require both a systematic monitoring based on the ever-increasing sampling and high performance of gamma ray spectroscopy. On the ground of these requirements a new low background fully automated high-resolution gamma-ray spectrometer MCA_Rad has been developed. The design of Pb and Cu shielding allowed to reach a background reduction of two order of magnitude with respect to laboratory radioactivity. A severe lowering of manpower cost is obtained through a fully automation system, which enables up to 24 samples to be measured without any human attendance. Two coupled HPGe detectors increase the detection efficiency, performing accurate measurements on sample volume (180 cc) with a reduction of sample transport cost of material. Details of the instrument calibration method are presented. MCA_Rad system can measure in less than one hour a typical NORM sample enriched in U and Th with some hundreds of Bq/kg, with an overall uncertainty less than 5%. Quality control of this method has been tested. Measurements of certified reference materials RGK-1, RGU-2 and RGTh-1 containing concentrations of K, U and Th comparable to NORM have been performed, resulting an overall relative discrepancy of 5% among central values within the reported uncertainty., 21 pages, 4 figures, 6 tables

Abstract

Coronary stent thrombosis (CST) is a major concern of interventional cardiology. Several risk factors for CST have been identified, but as a whole they do not explain the pathophysiology of CST. This study was designed to investigate whether acute infection-inflammation could facilitate the occurrence of CST. Forty-one patients, aged 66.6 +/- 11 years, consecutively admitted to our catheterization laboratory for acute, subacute or late CST, were retrospectively analysed. Transient acute infection-inflammation on admission for CST was diagnosed by predefined criteria. Prevalence of known risk factors for CST was also investigated. Twenty-one patients (51%) met predefined criteria for the occurrence of acute infection-inflammation. On admission, in these patients, levels of systemic humoral and cellular inflammatory markers were significantly higher than those of patients without recent or ongoing acute infection-inflammation (p0.05 for all). 62% of patients with acute infection-inflammation had less than two known risk factors for CST whereas only 37% patients without infection-inflammation showed less than two risk factors (p = 0.03) and showed more frequent interruption of antiplatelet treatment (17 vs. 2.4%, p = 0.02), mean longer stent length (20.5 +/- 4.8 vs. 16.5 +/- 5.1 mm, p = 0.02) and lower left ventricular ejection fraction before CST (42.9 +/- 14 vs. 47.3 +/- 11%, p = 0.02). In conclusion, acute infection-inflammation could play a role in facilitating the occurrence of CST in a subgroup with low risk profile for known risk factors. Our findings, if confirmed, could suggest new opportunities for prevention and treatment of CST.

Abstract

The observation of $^{26}$Al gives us the proof of active nucleosynthesis in the Milky Way. However the identification of the main producers of $^{26}$Al is still a matter of debate. Many sites have been proposed, but our poor knowledge of the nuclear processes involved introduces high uncertainties. In particular, the limited accuracy on the $^{25}$Mg($\alpha$,n)$^{28}$Si reaction cross section has been identified as the main source of nuclear uncertainty in the production of $^{26}$Al in C/Ne explosive burning in massive stars, which has been suggested to be the main source of $^{26}$Al in the Galaxy. We studied this reaction through neutron spectroscopy at the CN Van de Graaff accelerator of the Legnaro National Laboratories. Thanks to this technique we are able to discriminate the ($\alpha$,n) events from possible contamination arising from parasitic reactions. In particular, we measured the neutron angular distributions at 5 different beam energies (between 3 and 5 MeV) in the \ang{17.5}-\ang{106} laboratory system angular range. The presented results disagree with the assumptions introduced in the analysis of a previous experiment., Comment: 9 pages, 9 figures - accepted by EPJA
